A 90-day decision-psychology programme for traders and investors

The programme moves through three phases: Foundation (days 1–30) — build your decision-audit baseline and establish core journaling disciplines; Optimisation (days 31–60) — sharpen bias detection and refine pre-trade discipline through targeted countermeasures; Mastery (days 61–90) — integrate your decision system and sustain process-first discipline under real conditions.

The player above carries the working tools: calendar export (.ics), a print edition, CSV and full-progress export — and everything you log stays in this browser.

How this programme adapts

Once a week, the player runs a short check-in and reads the week you actually logged — not the week the plan assumed. Every check-in lands on one of the adjustments below. These are the engine's own rules, rendered word for word.

  1. Consolidation week

    Consistency comes first. This week holds your current programme exactly, with no new exercises added until your journaling is more regular.

  2. Rebuilding the journaling habit

    Without a record of your reasoning, the process-review work cannot build. Add five minutes to your daily entry time this week and focus on completeness over length.

  3. Reinforcing process discipline

    Low discipline scores signal that the process checks are not running consistently. Add five minutes to your pre-session preparation this week and revisit your checklist.

  4. Strong process week

    Your discipline scores and log completion both show a strong week. Reduce preparation time by five minutes and use the space for a brief end-of-week pattern review instead.

  5. On track

    Your numbers are in the expected range. This week continues with the scheduled programme.

Pattern insights are gated behind your own record: the first unlocks after 5 logged days, and every insight states the evidence it stands on. Milestone reviews at day 30, day 60, day 90 read your whole record and choose their coaching from it.

Month 1 — Foundation · Days 1–30

Build your decision-audit baseline and establish core journaling disciplines

Module 1Decision Audit BaselineDays 1–7
Day 1 · Lock Your Decision Journal 15 min

Note before beginning: this is decision-psychology training, not financial advice, and trading involves risk of loss. Your most important tool in this protocol is a dedicated decision journal, a plain notebook or document where you record your reasoning before you act. Introduce this habit today by opening your journal and writing your very first entry: the date, what you are considering, and why. Over the 90 days you will build five concrete assets: a calibration log, a decision journal, a FOMO countermove protocol, a post-trade review template, and a tested rule set — each one yours to keep using after the programme ends.

  • Open a dedicated decision journal and write your first entry today: date, what you are considering, and your reasoning at this moment
  • Write one sentence about your most recent decision and what information you had when you made it
Day 2 · Map Your Last Three Decisions 20 min

Look back at three real decisions you made in the last two weeks, whether a trade, a position-size change, or a decision to wait. For each one, write what information you had at the time and what you expected to happen. You are building a factual baseline of your own decision process, not evaluating outcomes yet.

  • Log three recent decisions in your journal: what the situation was, what information you had, and what you expected
  • Note for each decision whether you wrote down your reasoning before acting
Day 3 · Identify a Loss You Held Too Long 15 min

Think back to a position or decision you held past the point where your original reasoning no longer applied. Documenting this specific case, not as self-criticism but as a factual record, is the starting point for recognising your own disposition patterns. Write what was happening in your thinking at the time you chose not to close it.

  • Describe one specific case in your journal where you held a losing position longer than your plan intended
  • Write what you were telling yourself at the time and what finally changed your decision
Day 4 · Your Emotional State at Entry 10 min

Before any significant decision, your internal state, whether you are anxious, confident, distracted, or calm, is a live variable that shapes how you weight information. Today you introduce a brief daily mindset check: two minutes each morning to rate your readiness on a scale of one to five before you engage with markets or decisions. Awareness of your state precedes any adjustment to it.

  • Each morning before your trading session, rate your emotional readiness from 1 to 5 and write one sentence explaining your score
  • Complete your first mindset check now and note any specific mental states that feel relevant today
Day 5 · The Winning vs Losing Asymmetry 15 min

Recall a recent gain you closed and a recent loss of similar size that you held. Compare how each felt at the time of the decision. This exercise draws on the core observation of prospect theory: that losses carry greater emotional weight than equivalent gains, which can distort the symmetry of your decision process. Write what you observe in your own experience.

  • Recall a recent gain you closed and compare your emotional state at exit with a loss of similar size that you held, and write both descriptions in your journal
  • Write one sentence describing the difference in how each decision felt, without judging whether you were right or wrong
Day 6 · Baseline Confidence Audit 20 min

Before you can calibrate your confidence, you need a baseline reading of how accurate it has been. Today you examine five recent predictions or decisions and, for each one, write the confidence level you remember feeling at the time alongside what actually happened. This is an accuracy audit, not a performance review.

  • List five recent predictions or decisions in your journal and assign a rough confidence level (low, medium, or high) to each as you remember feeling at the time
  • Check the actual outcome for each and note whether the outcome matched your confidence level
Day 7 · Week 1 Self-Review 20 min

You have completed your first week of decision auditing. Take fifteen minutes today to re-read your entries from the past six days and look for any recurring patterns, recurring language, or recurring situations. The first pattern you notice is often the most instructive one to track going forward.

  • Re-read your journal entries from days 1 through 6 and write a brief summary of the patterns you observe
  • Identify one specific tendency you want to watch more closely in week 2
Module 2Trade Journal RitualDays 8–14
Day 8 · The Pre-Trade Checklist 15 min

A pre-trade checklist works as a structured pause between impulse and action, giving your reflective mind a chance to engage before a decision executes. Today you introduce this as a permanent habit: completing three check-in steps before any position entry or significant decision. You will sharpen the specific questions in week 4, but the ritual starts now.

  • Before any position entry or significant decision, pause and complete three steps: write your reasoning, confirm the decision fits your current plan, and note your mindset score
  • Run through your three steps for one recent or hypothetical decision and write your answers in full
Day 9 · Record Your Reasoning, Not Just the Trade 15 min

Most trade logs record price, size, and entry date. What they rarely capture is the specific reasoning chain that led to the decision. Today you practise writing a full reasoning entry for one real or hypothetical position, focusing on what information you had, what you expected, and what would falsify your view. This level of specificity is what makes post-trade review useful.

  • Write a full reasoning entry for one current or recent trade: the specific information you had, what you expected, and the condition that would tell you your reasoning was wrong
  • Review your entry and circle any places where your reasoning is vague or depends on information you do not actually have
Day 10 · The Prediction Log 15 min

Overconfidence is most visible in retrospect, but tracking it requires recording your confidence at the time of prediction, before the outcome is known. Today you begin logging specific predictions alongside your stated confidence level, so that over the coming weeks you can compare what you expected with what occurred. Write the prediction and confidence level first, outcome only when it resolves.

  • Record three specific predictions about near-term developments in your trading context, each with an explicit confidence level from 1 to 5
  • Set a reminder to check the accuracy of each prediction once it resolves and log the result in the same entry
Day 11 · Identifying Hindsight in Your Journal 15 min

Hindsight bias makes past decisions look more predictable than they were, distorting your ability to learn accurately from experience. Today you review your journal entries from the past week and look for language that rewrites the past, phrases drawn from knowledge you had only after the outcome. Catching this pattern in writing is the first countermeasure.

  • Re-read your entries from the past week and note any phrases that describe your past self as knowing something that was only clear in hindsight
  • Rewrite one of those sentences to describe only what you actually knew at the time of the decision
Day 12 · When You Changed Your Mind 15 min

Changing your mind is not a sign of weak decision-making. The question is what caused the change: new information, or the discomfort of sitting with uncertainty and the noise of short-term movement. Today you document one recent decision reversal and examine what specifically drove it, separating information-based updates from state-based ones.

  • Describe one recent case in your journal where you changed a decision or plan and write what specifically triggered the change
  • Label the trigger as either information-based, where new facts arrived, or state-based, where your emotional state shifted
Day 13 · Separating Process from Outcome 15 min

Research on outcome bias shows that evaluating decisions by their results, rather than by the quality of the process at decision time, systematically distorts what you learn from your own history. Today you pick two recent decisions and score each on the quality of the reasoning process only, without reference to the outcome. This is the discipline the later weeks build on.

  • Select two recent decisions and score each on process quality alone: did you have clear criteria, written reasoning, and a pre-stated exit condition?
  • Note which score surprised you more and write one sentence explaining why
Day 14 · Week 2 Journal Audit 20 min

You have now completed two weeks of decision journaling. Today your task is to look across all your entries and count how many contain a clear reasoning statement written before the outcome was known. This count is your process completeness score, and it is the metric you will track, not your win or loss rate.

  • Count how many of your journal entries this week contain a reasoning statement written before the outcome, versus entries that only describe what happened
  • Write a brief note on what the balance tells you about your current journaling practice
Module 3Loss Aversion MappingDays 15–21
Day 15 · Weekly Bias Audit 20 min

Pattern recognition across multiple decisions, rather than within a single trade, is how individual biases become visible. Today you introduce a weekly bias audit: a fifteen-minute review of the past week's decisions, specifically looking for instances of loss aversion, overconfidence, and recency-driven reasoning. This becomes a permanent habit in your programme from this point forward.

  • Each week, spend fifteen minutes reviewing your past seven days of journal entries and flag any entries that show signs of loss aversion, overconfidence, or recency-driven reasoning
  • Complete your first bias audit now, reviewing days 8 through 14, and write a brief note on what you find
Day 16 · The Asymmetric Pain Test 15 min

Recall the sting of a loss of a specific amount and compare it to the pleasure of gaining that same amount. Most people find the loss registers more strongly, and the degree of that asymmetry varies significantly by individual. Writing down where your personal asymmetry sits gives you a concrete reference point for watching how it operates in live decisions.

  • In your journal, describe a specific gain and a specific loss of roughly equal size and rate the emotional weight of each on a scale of 1 to 5
  • Write one sentence describing what the difference in those scores suggests about your own loss aversion pattern
Day 17 · When Did You Hold a Loser? 15 min

The disposition effect is not a character flaw but a predictable pattern that emerges from how we process losses relative to reference points. Today you document one specific instance where you held a position or commitment past the point where your original reasoning had already been invalidated. The goal is a factual account of the mechanics, not a verdict on the decision.

  • Document one specific instance in your journal where you held a losing position longer than your original plan called for
  • Write the reasoning you were using to justify the hold and what finally prompted the exit
Day 18 · When Did You Sell Too Early? 15 min

The flip side of the disposition effect is exiting winning positions before they have run to the target your original reasoning supported. Today you recall a case where you closed a winning position earlier than planned and examine what was driving that decision. Identifying both sides of the disposition pattern gives you a more complete picture of how it operates in your own decisions.

  • Describe one case in your journal where you closed a position with a gain before your original target was reached
  • Write what you were feeling at the moment of that early exit and whether the outcome changed your view of whether the decision was sound
Day 19 · Reference Point Inventory 15 min

Prospect theory shows that we evaluate outcomes relative to a reference point, whether an entry price, a portfolio high, or an expected level. Today you identify the reference points you are currently carrying for any active positions or pending decisions, because the location of a reference point directly shapes how gains and losses register emotionally.

  • List the reference points you are currently using for your active positions or decisions, such as entry price, prior high, or target level
  • Write one sentence for each reference point noting whether it is still the most rational anchor or whether it might be distorting your current view
Day 20 · The Exit Rule Written in Advance 15 min

Pre-committing to an exit condition before entering a position is one of the most direct process-level responses to the disposition effect. When the exit rule is written before entry, the decision is made without the emotional weight of a live loss on the line. Today you practise this by writing a specific exit condition for one current or hypothetical position.

  • Write a specific exit condition for one current or hypothetical position, stating exactly what would tell you the original reasoning is no longer valid
  • Review this condition and confirm it is based on the information available at the time of entry, not on subsequent price movement
Day 21 · Loss Aversion Pattern Summary 20 min

You have spent the last week examining how loss aversion operates in your own decision history. Today you synthesise what you have found into a personal loss pattern profile: a brief written description of where and how loss aversion most commonly shows up in your decisions. This profile serves as a reference point throughout the rest of the programme.

  • Write a one-paragraph personal loss pattern profile summarising what you have learned about your own loss aversion tendencies over the past three weeks
  • Identify the single most common form it takes in your decision-making and write one specific countermeasure you intend to use
Module 4Pre-Trade DisciplineDays 22–30
Day 22 · The Position-Size Anchor 15 min

Pre-commitment rules for position size serve as a structural check against in-the-moment pressure to oversize when confidence is high or undersize when anxiety is elevated. Today you introduce the habit of confirming your size against a written rule before any entry. Note: this is a process discipline, not a sizing recommendation or financial advice.

  • Before any position entry, confirm your sizing against a written rule you have set in advance and record whether you followed it
  • Write out your current informal sizing approach in one sentence and note whether it constitutes a rule or a general guideline
Day 23 · The Three-Question Gate 20 min

Your pre-trade checklist gains its force from the specific questions it asks. Today you write out three mandatory questions that any trade or significant decision must answer before execution. These questions should require written, reasoned answers rather than simple yes-or-no signals, and they will form the formal structure of your pre-trade habit going forward.

  • Write three specific mandatory questions that any trade or decision must answer before you act, and enter them into your journal as your official checklist
  • Run last week's best-documented decision through all three questions and check whether it would have passed
Day 24 · Red Conditions List 15 min

Alongside conditions that permit trading, equally useful is a list of conditions that should lead you to pause or step back entirely, whether a mindset score below 2, a particular emotional pattern, or a sequence of consecutive losses. Writing these conditions in advance, before you are in them, is far more effective than trying to recognise them in the moment.

  • Write three conditions under which you will pause your trading session and return to journaling before continuing
  • Review your mindset check entries from the past week and note whether any sessions began under conditions that would now be on your red list
Day 25 · Dry Run the Checklist 15 min

Before testing your checklist in live conditions, it is useful to run it against a past or hypothetical decision to check whether it is specific enough to be actionable. Vague questions produce vague answers that do not actually constrain behaviour. Today you identify any questions in your checklist that need sharper criteria.

  • Run your three-question checklist against a recent trade or a hypothetical one and write out your answers in full
  • Identify which question produces the least specific answer and rewrite it with a more concrete criterion
Day 26 · When a Rule Broke Down 15 min

Rules do not fail because they are wrong. They fail because in-the-moment conditions make them feel inapplicable. Today you identify one recent case where you had an informal rule and set it aside, and you examine the reasoning that justified the exception. Understanding how exceptions happen is the prerequisite for making rules more robust.

  • Describe one recent case in your journal where you had an informal rule and chose not to follow it
  • Write the reasoning you used to justify the exception and note whether that reasoning would still appear sound to you now, outside the moment
Day 27 · The Waiting Period Test 10 min

A simple friction-based approach for impulsive decisions is a mandatory waiting period: ten minutes between the impulse to act and the execution of that action. This brief pause is intended to shift the decision from a reactive state to a more deliberate one without requiring complex analysis. Today you practise logging the gap between impulse and action.

  • Identify one decision or potential trade from today or yesterday that felt impulsive and write what your reasoning looked like during the impulse moment
  • Write what your view of that same decision looks like now, with ten minutes or more of distance from the impulse
Day 28 · Checklist Completeness Review 15 min

One week in with your formal pre-trade checklist, today is the first review of how consistently it is running. Habit consistency at this stage matters more than checklist perfection. A checklist that runs every time with three imperfect questions is more useful than a perfect checklist that runs only when convenient.

  • Review your journal entries from days 22 through 27 and count how many sessions began with a completed pre-trade checklist
  • Write one specific change you will make to improve checklist consistency in the coming week
Day 29 · Month 1 Reflection 20 min

Three weeks in, you have built the core observation layer of this programme: a decision journal, a mindset check, a pre-trade checklist, a weekly bias audit, and a position-size anchoring habit. Today you revisit your first week and write one paragraph comparing what you observed then with how you are observing decisions now. The difference is the measure of your progress so far.

  • Re-read your entries from days 1 through 7 and write a short note on what you observe differently about your own decision-making now
  • Identify one pattern you noticed in week 1 that you now understand more specifically
Day 30 · Foundation Complete 20 min

Today marks the end of month 1 and Camp I. You have established the audit infrastructure that the rest of the programme builds on. The most important thing you did this month was not any single exercise but the accumulation of a genuine record of your own decision process. Month 2 will target specific bias patterns with that record as its material.

  • Write a one-paragraph personal discipline statement describing what you are working on, why process matters to you, and what you intend to track in month 2
  • Confirm your journaling habit is in place for the coming month and mark your calendar for your week 5 check-in

Month 2 — Optimisation · Days 31–60

Sharpen bias detection and refine pre-trade discipline through targeted countermeasures

Module 5Overconfidence DetectionDays 31–37
Day 31 · Confidence Rating at Entry 10 min

Recording your confidence level at the moment of a decision, before you know the outcome, is the starting point for calibration work. Without this record, confidence assessment is subject to hindsight, and you cannot learn where your confidence is well-founded versus where it exceeds your information. Today you introduce the habit of logging a confidence level alongside every decision entry.

  • At the moment of any trade entry or significant decision, record your confidence level from 1 to 5 in your journal before the outcome unfolds
  • Look back at your prediction log from day 10 and note whether the confidence levels you recorded there appeared accurate in retrospect
Day 32 · The Calibration Exercise 20 min

A well-known calibration exercise asks you to state ranges around your estimates that you believe have a high probability of containing the true value. Most people produce ranges that are too narrow, reflecting overconfidence in the precision of their estimates. Today you practise this with five estimates drawn from your own trading context.

  • Write five specific estimates about your trading context, each with an explicit high-probability range rather than a single point forecast
  • Return to this entry once each estimate resolves and note how many of your ranges contained the true value
Day 33 · Confidence vs Outcome Match Review 20 min

You have been logging confidence ratings for a few weeks. Today you look back at every prediction log entry you have made and compare your stated confidence levels to what actually occurred. The question is not whether your predictions were right but whether your confidence was appropriate to your information. That ratio is what calibration training addresses.

  • Review all your confidence-rated entries from days 10 through 32 and count how often your stated confidence appeared to match the accuracy of the outcome
  • Write one sentence describing the direction of any systematic error: do you tend toward high confidence, low confidence, or inconsistent confidence?
Day 34 · The Uncertainty Acknowledgment 15 min

Calibration research suggests that one of the more robust approaches to overconfidence is actively engaging with genuine counterarguments before acting. Today you install a pre-trade habit: before entering any position or significant decision, write one sentence of authentic disagreement with your own view, the strongest reason a thoughtful opponent would give for the opposite position. Writing it in advance, when you are not yet in the trade, makes the counterargument more honest than one constructed in hindsight.

  • Before any trade entry or significant decision, write one sentence stating the strongest genuine counterargument to your current position and add it to your pre-trade checklist as a standing step
  • Apply this step now: choose one current or recent decision and write the most credible opposing argument in one sentence, then note whether it changes your confidence level
Day 35 · Disagreement as Information 20 min

A credible counterargument to your current view is not a threat but a data point. Seeking out and engaging with well-reasoned opposing views is one of the few robust approaches to reducing overconfidence described in the calibration literature. Today you find one serious argument that contradicts your current position and engage with it in writing.

  • Identify one well-reasoned view that contradicts your current trading position or market outlook and write a fair summary of its strongest version
  • Write your response to that view, focusing on the specific evidence that would distinguish between the two positions
Day 36 · The Overfitting Check 15 min

Overfitting is the tendency to see patterns in data that reflect noise rather than signal, and it is a particular risk when your analysis is motivated by a position you already hold. Today you review one piece of analysis that supports your current view and ask specifically whether the conclusion would hold if it had been done by someone with no stake in the outcome.

  • Select one recent analysis or piece of reasoning that supports a current position and list the evidence it rests on
  • Write one sentence asking: if the conclusion had been the opposite, would I have interpreted this same evidence differently?
Day 37 · Week 5 Calibration Snapshot 15 min

By the end of week 5 you have enough predictions logged to take a calibration snapshot: a count of how often your stated confidence level appeared appropriate to the accuracy of the prediction. This number is informational, not evaluative. Its purpose is to give you a concrete baseline to compare against in weeks 9 and 12.

  • Calculate the proportion of predictions from this week where your stated confidence appeared appropriate to the outcome and write it down as your calibration baseline
  • Write one sentence on whether your tendency appears to be toward high confidence, low confidence, or inconsistent confidence
Module 6Recency Bias CountermeasuresDays 38–44
Day 38 · The FOMO Log 10 min

The impulse to enter a position because a move is already underway is one of the most common sources of unplanned entries in active trading. Today you introduce the end-of-session FOMO log: a brief daily note on any urges to chase moves that you noticed, what triggered them, and what you decided. Naming the trigger in writing is the first step toward a consistent response. If you are in a low-activity period, replace this exercise with a paper-trading log: track one hypothetical position per day through the current session, applying your checklist as if real. The process practice is identical.

  • At the end of each trading session, log any urges to chase moves that you noticed: what triggered them, how strong they felt from 1 to 5, and what you did
  • Complete your first FOMO log entry now by recalling one impulse from today or yesterday that had the character of chasing a move
Day 39 · When Recent Events Dominated 15 min

Recency bias operates by making the most recent vivid outcome disproportionately influential over your assessment of what is likely next. Today you identify one recent decision where a recent event, a large win, a sharp loss, or a notable news development, appears to have weighted your reasoning more than the longer-term base rate would justify.

  • Identify one decision from the past two weeks where a recent vivid event appears to have been more influential than the longer-term context would warrant
  • Write what the base rate for that type of situation looks like and how it compares to the recent episode you were weighting
Day 40 · The Base Rate Check 15 min

Base rates are the frequencies with which outcomes occur across a large number of similar cases, and they provide an anchor against the distortions of vivid recent events. For any significant current decision, looking up or estimating the relevant base rate gives you a check on whether your assessment is being shaped by recent experience more than the wider pattern.

  • For one current or recent decision, identify the relevant reference class and estimate or look up the base rate for the outcome you are expecting
  • Write whether your current confidence is above or below what the base rate would suggest and note what accounts for the difference
Day 41 · Pattern-Seeking Audit 15 min

Recency bias often shows up in journal language as pattern claims built from too few observations, phrases like 'it always does this after' drawn from two or three recent examples. Today you scan your entries from the past two weeks for this kind of language and note where a claimed pattern is actually a run of vivid recent events.

  • Re-read your journal entries from days 22 through 40 and circle any phrases that claim a pattern based on a small number of recent observations
  • For each phrase you circle, write the minimum number of observations you would need before trusting that pattern as a reliable guide
Day 42 · The Cooling-Off Entry 10 min

When a strong impulse is triggered by a recent event, a simple written note before acting can interrupt the impulse-to-action sequence. The cooling-off entry is not a decision to wait but an observation: noting what you are feeling, what triggered it, and what your written criteria actually say about the situation. Today you practise this with a real or recent impulse.

  • Recall a recent impulse triggered by a market event and write a cooling-off entry describing what you were feeling, what triggered it, and what your original criteria said about the situation
  • Note whether the criteria you had written in advance would have supported or blocked the impulse
Day 43 · Sequence Independence 15 min

Many short-term outcomes are statistically independent of each other, meaning a sequence of good or bad results tells you less about what is likely next than it may feel. Recency bias treats recent sequences as predictive, which can lead to expecting continuation after runs. Today you write out three outcomes that are likely independent and trace what that independence means for your decision.

  • Identify three outcomes in your trading context that are likely to be statistically independent and write what that independence implies for weighting recent sequences
  • Write one sentence on whether any current decision is implicitly relying on a sequence pattern that independence would undermine
Day 44 · Recency Countermeasure Review 15 min

You have spent a week examining how recent events shape your reasoning. Today you summarise what you have learned about your personal recency triggers, the specific types of events or sequences that reliably pull your attention and weight your decisions. This personal trigger inventory will be useful throughout the rest of the programme.

  • Write a brief summary of the two or three most common recency triggers you have identified in your own decision log over the past week
  • For each trigger, write one specific countermeasure you intend to use when you notice it operating
Module 7FOMO Exposure DrillsDays 45–51
Day 45 · Name the FOMO Triggers 15 min

FOMO operates differently for different people: some are most vulnerable to watching a market move quickly, others to hearing reports of gains, and others to a period of inactivity followed by a burst of apparent opportunity. Today you examine your own FOMO log and identify the specific situations that most reliably trigger that impulse pattern in you.

  • Review your FOMO log entries from days 38 through 44 and identify the two or three situations that appear most consistently as triggers
  • Write a brief description of each trigger situation so you can recognise it more quickly in future
Day 46 · The Missed Opportunity Log 15 min

Missing a market move is not the same as taking a loss, even though the emotional experience can feel similar. Today you document one move you were aware of but did not enter and examine what your criteria would have said about it at the time of the opportunity. The goal is to separate the emotional experience of missing from a genuine assessment of whether the entry met your plan. If you are in a low-activity period, replace this exercise with a paper-trading log: track one hypothetical position per day through the current session, applying your checklist as if real. The process practice is identical.

  • Document one recent move you were aware of but did not enter and write what your pre-trade checklist and criteria would have said about it at the time
  • Write whether missing this move represents a process gap, where valid criteria were met but you missed the entry, or a process success, where the entry did not meet your criteria
Day 47 · Opportunity Cost Is Not a Loss 10 min

The asymmetric weighting of losses over gains means missing a move can generate a psychological response that resembles the experience of an actual loss, even though no capital was at risk. Recognising this distinction in real time can prevent missed opportunities from generating compensatory risk-taking decisions outside your criteria.

  • Write a brief entry in your journal distinguishing between an actual loss, where capital was at risk and lost, and a missed opportunity, where capital was never at risk
  • Identify one case from the past week where you noticed the feeling of a missed opportunity and write whether it led to any impulsive decisions
Day 48 · The FOMO Countermove Protocol 20 min

Rather than relying on willpower to suppress impulse-driven entries, a written protocol gives you a specific sequence to follow when the impulse arises. Today you design your personal FOMO countermove protocol: three steps you will take in sequence every time you notice a trigger, written and ready before you are in the heat of one. If you are in a low-activity period, replace this exercise with a paper-trading log: track one hypothetical position per day through the current session, applying your checklist as if real. The process practice is identical.

  • Write your three-step personal FOMO countermove protocol: what you will do in sequence when you recognise a trigger, starting with a pause and ending with a criteria check
  • Run your protocol against one real trigger from your log this week and note whether it provides enough structure to create a consistent pause
Day 49 · Social Comparison in the Feed 10 min

Information about others' gains can act as a comparison trigger, making your own recent results feel inadequate and generating pressure to act outside your criteria. Today you notice and log any instances this week where information about others' performance influenced your thinking, without judging the influence as good or bad.

  • Log any instances from the past week where information about other traders' or investors' results influenced your thinking or created pressure to act
  • Write one sentence on whether that influence was compatible with your written criteria or whether it was operating outside them
Day 50 · FOMO Drill: Sit Out the Move 15 min

The most direct practice for decision discipline under FOMO pressure is to deliberately notice a move you might want to chase and consciously run your criteria rather than reacting to movement. This is a process exercise, not a recommendation about any specific entry. Today you practise one such deliberate decision. If you are in a low-activity period, replace this exercise with a paper-trading log: track one hypothetical position per day through the current session, applying your checklist as if real. The process practice is identical.

  • Identify one move in your trading context that tempts you and run it through your pre-trade checklist criteria explicitly and in writing
  • Write your decision, whether it meets criteria or not, and how the process of running the checklist affected the experience of the impulse
Day 51 · Mid-Protocol FOMO Audit 20 min

You are now at the mid-point of the protocol. Your FOMO log, started on day 38, contains two weeks of entries across a range of market conditions. Today you review those entries in full and identify the single most common trigger and the countermeasure that has been most useful so far.

  • Review all your FOMO log entries from days 38 through 50 and identify the most common trigger type and the most common strength rating
  • Write one sentence describing the countermeasure that has been most consistent and useful for you so far
Module 8Post-Trade Review SystemDays 52–60
Day 52 · The Process Score 10 min

A process score is a rating of how well your decision process ran, independent of the outcome. Introducing this habit now means you will have enough logged process scores to review patterns in month 3. Rate your process on a scale of one to five after each trade or significant decision, using your pre-trade checklist as the primary input.

  • After each trade or significant decision, write a process score from 1 to 5 reflecting whether your checklist ran completely, your reasoning was written in advance, and your criteria were applied
  • Score the last three decisions you made using this rubric and note any patterns in where process quality was highest or lowest
Day 53 · Separating Decision Quality from Outcome 15 min

A well-reasoned decision with a poor outcome and a poorly reasoned decision with a good outcome are both common in environments with high uncertainty. Today you explicitly practise separating these two dimensions by selecting three recent trades and scoring each twice: once for process quality and once for outcome quality. The divergence between those scores is instructive.

  • Select three recent trades or decisions and assign each a separate process score and outcome score from 1 to 5
  • Write one sentence on which case showed the largest divergence between process and outcome and what that divergence suggests
Day 54 · The Good Process, Bad Outcome Case 15 min

The most challenging application of process-first thinking is when your process was sound and your outcome was poor. This combination is informative precisely because it shows your process running correctly under conditions where the outcome was in the range of expected variance rather than a product of a process error. Today you find and document one such case.

  • Identify one case where you followed your process well and the outcome was still unfavourable, and write a factual account of the decision and its outcome
  • Write what you believe the process quality would have been rated if you had scored it before the outcome was known
Day 55 · The Bad Process, Good Outcome Case 15 min

A poor decision process can produce a favourable outcome by chance, and this is one of the hardest patterns to learn from because the positive outcome can reinforce the faulty process. Today you identify one case where your process was below your own standard and the outcome was still favourable, and you examine what risk you were carrying that did not materialise.

  • Identify one case where you made a decision with a weak process and the outcome was favourable, and write a factual account of what the process was missing
  • Write what risk was present in the situation that the favourable outcome did not reflect
Day 56 · Building Your Post-Trade Template 20 min

A structured post-trade review template ensures that every review asks the same questions and produces comparable data over time. Today you design a four-field template that you will use for post-trade reviews going forward. The fields are: the original reasoning, the process score, the outcome, and one observation for future reference.

  • Design your four-field post-trade review template and enter it into your journal as a permanent format
  • Complete the template for one recent trade, filling in all four fields in writing
Day 57 · The Hindsight Immunity Check 15 min

To prevent hindsight from contaminating your process assessment, the most reliable sequence is to write the process score before looking at the outcome. Today you practise this explicitly: write your process assessment first, then check what happened. The experience of doing this in the right order is itself informative about how outcome knowledge changes evaluation.

  • Before checking the current status of one open or recently closed position, write your process assessment and process score for the original entry decision
  • Now check the outcome and note whether knowing the outcome changes how you want to rate the process, and what that pull tells you
Day 58 · Process Scores This Week 15 min

You have been logging process scores for a week. Today you calculate the average of those scores and look for any patterns: are scores higher early in the week or late, after periods of inactivity or during busy sessions, when you checked your mindset score or when you skipped it? Process consistency across conditions is the target.

  • Calculate your average process score from days 52 through 57 and note any pattern in when scores were highest or lowest
  • Write one specific condition that appears associated with your highest process scores and one associated with your lowest
Day 59 · Month 2 Bias Audit 20 min

At the close of month 2, you have accumulated five weeks of more specific bias-targeted work. Today you run a full bias audit across all five areas: loss aversion, overconfidence, disposition effect, recency bias, and FOMO. Rate your current awareness of each from one to five and note where the pattern is most persistent in your log.

  • Rate your current awareness of each of the five bias areas from 1 to 5 based on your journal entries from days 31 through 58
  • Write which bias area you understand most specifically and which one still feels most opaque
Day 60 · Optimisation Complete 20 min

Today marks the end of month 2 and Camp II. You have run calibration exercises, extended your FOMO discipline, developed a post-trade review system, and built a clearer picture of where each bias pattern operates in your own decision history. Month 3 moves from observation and detection to rule construction and system integration.

  • Write one specific rule, phrased in if-then format, that is directly informed by something you learned about your own decision patterns in month 2
  • Identify the bias pattern where a rule-based approach would be most useful for your particular decision history

Month 3 — Mastery · Days 61–90

Integrate your decision system and sustain process-first discipline under real conditions

Module 9Calibration PracticeDays 61–67
Day 61 · Weekly Calibration Check 10 min

In month 3, calibration shifts from initial assessment to regular practice. Today you introduce the habit of a weekly calibration check: a brief review each week of the predictions you logged seven days ago and how accurate they turned out to be. This habit builds a real accuracy record over time rather than relying on memory. If you are in a low-activity period, replace this exercise with a paper-trading log: track one hypothetical position per day through the current session, applying your checklist as if real. The process practice is identical.

  • Each week, review the predictions you logged seven days ago and record whether each one resolved as expected, marking each accurate or inaccurate
  • Complete your first calibration check now by reviewing any predictions logged during days 54 through 60 and scoring their accuracy
Day 62 · Forecasting Under Uncertainty 20 min

Uncertainty is not the absence of information but a condition that requires explicit acknowledgement. Today you make five probability estimates about near-term developments in your trading context and assign each an explicit probability range rather than a point prediction. Ranges that acknowledge uncertainty are more calibrated starting points than confident point forecasts.

  • Write five specific probability estimates about developments you expect in the next one to two weeks, each stated as a range rather than a single number
  • Mark each estimate with the date and return to it once it resolves to score accuracy
Day 63 · The Reference Class Approach 20 min

The reference class approach involves identifying the broader category of situations your current decision belongs to and using the historical frequency for that category as an anchor. This outside-view check is one of the better-documented approaches to counteracting overconfidence in complex decisions, and it works by reducing the weight of your own inside-view analysis.

  • For one current decision, identify the reference class it belongs to, the broader category of similar decisions across many instances, and look up or estimate the base rate for the outcome you expect
  • Write whether your current confidence is above or below the reference class base rate and what specific information justifies any deviation
Day 64 · Updating on Evidence 15 min

A well-calibrated decision-maker updates their view when new information arrives, neither over-updating on noise nor under-updating to avoid admitting the original view was wrong. Today you identify one case from the past week where new information arrived that was relevant to a current position and examine whether your update was proportional to the information.

  • Identify one case from the past week where new information arrived that was relevant to a current position or decision, and describe what change in your view that information warranted
  • Write whether you updated your view, under-updated to avoid conflict with your prior, or over-updated beyond what the information warranted
Day 65 · The Outside View 20 min

The outside view asks you to step back from your specific analysis and consider what typically happens in situations like this one, before applying your particular reasoning. This is not a request to ignore specific information but to anchor your thinking in the reference class before adjusting. Today you apply this specifically to your most confident current position.

  • Take your most confident current position or view and write what the outside view, based on reference class reasoning, would say about the probability of the outcome you expect
  • Write how far your current confidence deviates from the outside view estimate and what specific information justifies that deviation
Day 66 · Calibration Log Review 15 min

Your calibration log now covers several weeks of predictions and outcomes. Today you review the full record and calculate what proportion of your high-confidence predictions, those rated 4 or 5, turned out to be accurate. This ratio is your high-confidence calibration score and gives a direct, objective read on whether your high-confidence judgments are warranted.

  • Review all predictions from days 10 through 65 rated at confidence 4 or 5 and calculate the proportion that turned out to be accurate
  • Write one sentence on whether the pattern suggests systematic overconfidence, reasonable calibration, or a domain where your confidence is better versus worse
Day 67 · Week 9 Calibration Summary 15 min

Several weeks of calibration logging give you a real signal about the accuracy of your confidence ratings, independent of whether individual trades were profitable. Today you write a one-sentence description of your current calibration pattern and identify one specific decision type where your confidence most consistently exceeds your accuracy. That is where rule-based checks will be most useful.

  • Write one sentence describing the pattern in your calibration log: does overconfidence appear across all domains, or is it specific to certain types of decisions?
  • Identify one specific decision type where your confidence consistently exceeds your accuracy and note what process check you will apply there going forward
Module 10Rule ConstructionDays 68–74
Day 68 · Rules as Pre-Commitment Devices 20 min

Pre-commitment rules are most useful when they are written specifically enough to remove ambiguity at the moment of decision. A rule that says 'be careful when emotional' is less actionable than a rule that says 'pause the session if mindset score is 2 or below'. Today you identify one recurring impulsive pattern in your log and write a specific rule that addresses it.

  • Identify one recurring impulsive tendency from your decision journal and write a specific if-then rule that addresses it
  • Test your rule against three recent situations where the impulsive tendency appeared and check whether the rule would have run correctly
Day 69 · The If-Then Format 20 min

The if-then format converts general intentions into specific, executable rules. 'I will be more disciplined' becomes 'If my mindset score is below 3, then I will complete a written reasoning entry before entering any position.' Today you rewrite three of your current informal intentions in explicit if-then format.

  • Take three informal intentions or guidelines from your trading practice and rewrite each as an explicit if-then rule
  • Check each rule for specificity: can you imagine being in the situation and knowing clearly whether the if-condition is met?
Day 70 · Testing Rule Robustness 20 min

A rule is only as useful as its behaviour under pressure. Today you take your three most important rules and run them through three historical scenarios from your trading log where the temptation to deviate was highest. The purpose is not to prove the rules are perfect but to find where they need sharpening.

  • Take your three most important if-then rules and apply each to a historical scenario from your journal where it would have been most tested
  • Write for each rule whether it held up under that scenario and, if not, what amendment would make it more robust
Day 71 · The Rule Exception Trap 15 min

The most common way rules break down is not direct violation but exception-making: the reasoning that this particular situation is different and the usual rule does not apply. Today you review your journal for any instances of exception-making and examine the quality of the reasoning used to justify each one. Exceptions can be correct, but they need the same rigour as the original rule.

  • Review your journal entries from days 22 through 70 and identify any case where you described a reason for not following a rule or guideline
  • Write the quality of the reasoning for each exception: was the case genuinely different, or was the exception made under emotional pressure?
Day 72 · Closing the Rule Gaps 20 min

Rule gaps are decision areas where you have no formal rule, leaving the decision to be made in the moment under whatever conditions happen to be present. Today you identify one recurring decision area in your practice where you have no formal rule and write a draft rule for it, accepting that the draft will need refinement from experience.

  • Identify one recurring decision area, such as how to respond to a rapid adverse move or when to add to a position, for which you currently have no formal rule
  • Write a draft if-then rule for that area, noting it as a draft and committing to test it over the next two weeks
Day 73 · Rule Conflict Resolution 15 min

When two rules apply to the same situation with different implications, the conflict must be resolved in advance rather than in the moment. Today you check your rule set for any cases where two rules might pull in opposite directions and write a priority order or a tiebreaker principle for each conflict you find.

  • Review your complete rule set and identify any two rules that could produce conflicting guidance in the same situation
  • Write a resolution for each conflict: either a priority order between the two rules or a specific condition that determines which one applies
Day 74 · Rule Set Version 1.0 25 min

Today you compile all your if-then rules, including your pre-trade checklist, mindset check conditions, position-size anchor, FOMO countermove protocol, and any new rules written this week, into a single document. This is version 1.0 of your personal decision rule set. It is a living document, not a finished product, and month 3 will continue to refine it.

  • Compile all your written if-then rules into a single document titled Rule Set Version 1.0 and enter it into your journal
  • Count the total number of rules in version 1.0 and note which bias area each rule addresses
Module 11System Stress-TestingDays 75–81
Day 75 · The Adversity Review 15 min

Adversity is when process discipline matters most and is hardest to maintain. Today you introduce the adversity review habit: a regular check specifically focused on decisions made under difficult conditions, whether a drawdown period, an unexpected loss, or a period of poor concentration. Identifying how your process held up under pressure is the key input for rule refinement.

  • Each week, identify one decision made under adverse conditions, pressure, fatigue, or losses, and review whether your process ran fully or was abbreviated
  • Complete your first adversity review now by selecting one recent decision made when conditions were less than ideal and evaluating your process quality in that instance
Day 76 · The Drawdown Scenario 20 min

A drawdown period places specific pressure on every element of process discipline: it raises the stakes of individual decisions, increases the temptation to take larger risks to recover, and makes rule-following feel costly. Today you write your specific, concrete process response to a sequence of consecutive losing sessions, and you write it before you are in one.

  • Write your specific process response to three consecutive losing sessions: what you will do differently in terms of session length, journaling, and checklist adherence during a drawdown
  • Check your written response against your rule set version 1.0 and confirm they are consistent
Day 77 · Stress-Testing Your Most Important Rule 20 min

Your most important rule is the one that addresses the situation where your process is most likely to fail. Today you identify that rule and apply it to the hardest scenario from your trading history where it would have been tested. The question is not whether the rule handles the easy cases but whether it holds when conditions are most demanding.

  • Identify your most important process rule and write the historical scenario where following it would have been most difficult
  • Write whether the rule as currently written would have held under that scenario and what amendment would make it more robust
Day 78 · The Emotional Override Scenario 20 min

Every rule set has a scenario where emotional pressure is most likely to override it. Today you identify one past case where your decision was driven primarily by your emotional state rather than your criteria, and you write a specific rule that addresses that scenario. Rules written for specific emotional override situations are more actionable than general rules about staying disciplined.

  • Describe one past case in your journal where your decision was shaped primarily by your emotional state rather than your written criteria
  • Write a specific if-then rule that would have created a pause or check in that exact scenario
Day 79 · The Accountability Structure 15 min

External accountability can increase rule-following consistency by creating a record that another person or a formal review process will see. Today you decide on one accountability mechanism for your rule set: a review partner you share your journal with, a scheduled written review, or a formal review process with a specific format. The choice depends on what is realistic for you.

  • Decide on one accountability mechanism for your decision journal and rule set and write it as a formal commitment in your journal
  • Set your first review appointment or share your first review entry according to your chosen mechanism
Day 80 · Full Rule Set Stress Test 25 min

Today you take your entire rule set version 1.0 and run it through five adversarial scenarios drawn from your own trading history, the five cases where your process was most tested. The goal is not to find that all rules hold but to identify the two or three rules that need strengthening before you write version 2.0.

  • Select five adversarial scenarios from your trading history and run each through your full rule set, noting which rules ran correctly and which were absent or failed
  • Write the two or three rules identified as needing strengthening and draft one amendment for each
Day 81 · System Health Check 20 min

With two months of data in your journal and a complete rule set tested, you can now do a structured health check across all five bias dimensions. Rating each dimension on a scale of one to five, where five means the pattern is well-addressed by your current system, gives you a map of where the remaining work in week 12 should focus.

  • Rate your current decision system across each of the five bias areas on a scale of 1 to 5 reflecting how well your current rules and habits address each
  • Identify the area with the lowest rating and write one specific improvement you will make to your system before day 90
Module 12Mastery IntegrationDays 82–90
Day 82 · The 90-Day Decision Arc 20 min

Today you return to day 1 and read your first journal entry. Three months ago you wrote about a decision without the systematic observation layer you have built since. Reading that entry now is an opportunity to see what has changed in how you observe and describe your own decision process, not in your market results but in the quality of your reasoning record.

  • Re-read your journal entry from day 1 and write a brief comparison of how you described your decision process then and how you would describe a similar decision now
  • Identify one specific element of your decision process that is most different from three months ago
Day 83 · Your Personal Bias Profile 25 min

Over ninety days you have accumulated a specific picture of how each of the five bias patterns operates in your own decisions. Today you write a personal bias profile: a summary describing each bias in terms of how it appears in your specific decision history, which triggers activate it, and which rules or approaches address it.

  • Write a personal bias profile covering each of the five areas: the specific form the bias takes in your decisions, the trigger situations, and the rule or approach you have developed for it
  • Note which bias area required the most work and which you feel most confident about managing going forward
Day 84 · The Forward Contract 20 min

A forward contract, in decision terms, is a written commitment made now about how you will decide in a specific future situation. Writing it now, outside the pressure of a live decision, is more robust than relying on in-the-moment resolve. Today you write three forward contracts, each specific to a situation your log shows is a recurring challenge.

  • Write three forward contracts for situations your log shows are recurring challenges, each in if-then format with a specific condition and a specific process response
  • Enter each forward contract into your rule set version 1.0 as new entries and note the date added
Day 85 · Journaling Consistency Review 15 min

Your journaling consistency across ninety days is the foundation that all other protocol work rests on. Today you count how many of the last eighty-four days contain a journal entry with a written reasoning statement and note what the pattern suggests about your consistency under different conditions. A record is most useful when it is maintained across all conditions, not only the easy ones.

  • Count how many of days 1 through 84 contain a journal entry with a written reasoning statement or process check
  • Identify the two conditions under which you were most likely to miss an entry and write one adjustment to your journaling habit that addresses those conditions
Day 86 · The Consistency Principle 15 min

Process consistency across varying conditions, not performance in any single period, is what the ninety-day programme is designed to build. Today you review your process scores from months 2 and 3 and look for the trend: are scores moving upward across the period, stable, or variable? The pattern is more informative than any individual score.

  • Review all your process scores from days 52 through 85 and write whether the trend is upward, stable, or variable
  • Identify one condition associated with your highest process scores and one associated with your lowest
Day 87 · Rule Set Version 2.0 25 min

Your rule set has been tested across two months of real conditions. Today you update it with everything learned in month 3, including the forward contracts from day 84, the amendments from the stress test in day 80, and observations from the adversity reviews. Version 2.0 is the rule set you carry beyond this programme.

  • Update your rule set with all amendments and new rules from month 3, including forward contracts, stress test amendments, and adversity review observations
  • Write a brief change log noting what is new in version 2.0 relative to version 1.0 and why each change was made
Day 88 · What a High-Quality Decision Looks Like 15 min

After eighty-eight days of examining your own decision process, you now have a specific, personal understanding of what high-quality decisions look like for you. Today you write this understanding in your own words, independent of outcomes. The definition should describe process elements: what was present when the process was running well.

  • Write a personal definition of a high-quality decision in your own words, based on what you have observed in your best-documented journal entries
  • Write what distinguishes a high-quality decision from a lucky one in your current understanding
Day 89 · Mastery Consolidation 20 min

As you approach the end of this programme, the most useful reflection is identifying the single most valuable discipline change you have made across ninety days, the one adjustment that most changed how you observe or act on your own decisions. This is not a list of everything you learned but the one change that mattered most.

  • Identify and write about the single most valuable discipline change you have made across the ninety days of this programme
  • Write one sentence on how you will sustain that change beyond the programme
Day 90 · Summit 30 min

Today marks the completion of the ninety-day arc. You have built a decision journal, a pre-trade checklist, a bias audit practice, a calibration log, a FOMO countermove protocol, a post-trade review system, and a personal rule set tested under real conditions. The protocol was designed not to produce a finished product but to build the habits and observation capacity that make ongoing development possible.

  • Complete a formal self-assessment across all five bias dimensions, rating where you started versus where you are now, and write it as a final entry in your journal
  • Write a personal discipline charter, one paragraph, describing your commitment to process-first decision-making and the specific practices you will continue

The evidence

The frameworks this programme is built on — each anchored to peer-reviewed research, cited with its DOI and verified against the Crossref registry at build time. Where the evidence has honest limits, the framework says so.

Prospect Theory and Loss Aversion

Kahneman & Tversky · Econometrica · 1979

The foundational framework describing how people evaluate outcomes relative to a reference point, with losses weighted more heavily than equivalent gains. In trading contexts this asymmetry shapes decisions around cutting losses, holding winners, and interpreting risk, and it underpins the disposition effect, FOMO responses, and exit-rule failures documented in the behavioural finance literature.

Overconfidence and Calibration in Markets

Barber & Odean · The Journal of Finance · 2000

Research examining tens of thousands of individual brokerage accounts found that trading frequency, driven by overconfidence in the precision of private information, is associated with higher transaction costs and reduced net returns. Calibration training addresses the systematic gap between perceived and actual accuracy by building an explicit record of prediction versus outcome.

Disposition Effect and Recency Bias

Shefrin & Statman · The Journal of Finance · 1985

The disposition effect describes the systematic tendency to realise gains too early and defer realising losses, documented in large-scale brokerage account data. Recency bias compounds this pattern by making recent vivid outcomes disproportionately influential over forward-looking decisions, producing overreaction to short sequences of good or bad results.

DOI: 10.1111/j.1540-6261.1985.tb05002.x

  • De Bondt & Thaler, 1985 — Market-level evidence that portfolios of extreme past losers outperform past winners over three-to-five-year horizons, consistent with systematic overreaction to prior information. doi:10.1111/j.1540-6261.1985.tb05004.x

Myopic Loss Aversion and Pre-Commitment

Benartzi & Thaler · The Quarterly Journal of Economics · 1995

Myopic loss aversion combines short evaluation horizons with the asymmetric weighting of losses over gains, producing excessive aversion to short-term volatility. Pre-commitment rules and extended evaluation windows are the primary countermeasures examined in the experimental literature, with written rules framed in advance acting as structural checks against in-the-moment loss sensitivity.

DOI: 10.2307/2118511

Outcome Bias and Decision Process Evaluation

Baron & Hershey · Journal of Personality and Social Psychology · 1988

Outcome bias is the tendency to evaluate the quality of a decision based on its eventual result rather than the information and reasoning available at decision time. This distorts post-trade learning by confounding process quality with outcome noise, and research on illusion of control shows that traders often overattribute outcomes to skill in conditions where chance is the primary driver.

Safety & fit

This 90-day protocol is a structured, educational programme in decision psychology and behavioural finance. It is not financial advice, not investment advice, and not medical advice. No instrument recommendation, return forecast, or trading strategy is expressed or implied. Trading and investing involve risk of loss. Every framework it draws on is referenced to peer-reviewed literature for educational context only.

Questions, answered

How much time does this take?

The Trading Protocol runs 90 days across 12 themed modules (about 13 calendar weeks). Each day asks for between 10 and 30 minutes of deliberate practice — the daily tasks are listed in the programme map on this page, so you can read the whole arc before you start.

How does the programme adapt to my week?

A weekly check-in reads the week you actually logged — not the week the plan assumed. Depending on the week you actually had, it lands on one of 5 adjustments: Consolidation week; Rebuilding the journaling habit; Reinforcing process discipline; Strong process week; On track. Milestone reviews at day 30, day 60, day 90 read your whole record so far.

Where is my progress stored?

Entirely in this browser. Your daily log, notes, and check-ins live in local storage on this device — no account, no server, and nothing you type is transmitted. You can export your full log as a CSV file or delete everything, at any time, from the My log tab.

Is this medical advice?

No. This is a structured, educational programme built on peer-reviewed research — it is not medical advice, therapy, or a substitute for professional guidance. The full disclaimer, and every framework the programme draws on with its DOI, is on this page.

What happens if I miss days?

The programme is built to absorb real weeks. The weekly check-in works from whatever you logged: a thin week adjusts the plan rather than failing you, and no adjustment ever deletes your record. The adaptation rules above describe exactly how each kind of week is handled.

Where does the evidence come from?

Every phase of the programme is grounded in 5 evidence frameworks — 10 peer-reviewed references in total, each cited with its DOI in the evidence section on this page and verified against the Crossref registry at build time. Where the evidence has honest limits, the framework says so.
