Flow
Attention is the scarcest resource in any demanding job, and most of us lose it without noticing where it went.
This pillar covers absorbed attention and how to produce it on demand, from deep work and the flow triggers to binaural beats and the Pomodoro Technique. Popular focus hacks are tested against the evidence, not taken on faith.

Reference
Look it up fast: every concept defined and traced, and the whole topic compressed onto a card.
Defined terms
Glossary
Every concept in the category, in plain language and traced to its source, each with its own picture.
FlowAttention Economy
Attention economy is the commercial and cognitive framework in which human attention is treated as a finite, tradeable resource.
FlowAttention Residue
Attention residue is the cognitive cost of switching tasks before completing them.
FlowCognitive Load
Cognitive load is the total demand placed on working memory when processing new information or solving a problem.
FlowDecision Fatigue
As choices accumulate, the quality and the willingness behind further decisions decline.
FlowDeep Work
Deep work refers to professional activity performed in a state of distraction-free concentration that pushes cognitive capabilities to their limit.
FlowDefault Mode Network
The default mode network is the brain's resting baseline.
FlowEisenhower Matrix
Eisenhower Matrix is a four-quadrant decision tool that classifies tasks by two axes: urgency and importance.
FlowEustress
Eustress is the beneficial form of stress characterised by a positive cognitive appraisal of a demanding situation.
FlowFlow State
Flow state is a discrete psychological condition in which a person becomes wholly absorbed in a demanding task, with effortless concentration, loss of self-consciousness, and distorted time perception.
FlowHyperfocus
Hyperfocus is a state of intense, involuntary absorption in a task during which all competing stimuli are effectively blocked from conscious awareness.
FlowMultitasking
Multitasking is the attempt to perform two or more cognitive tasks simultaneously.
FlowPomodoro Technique
Pomodoro Technique: Cirillo's 25-minute work-interval method.
FlowSelective Attention
Selective attention is the cognitive capacity to concentrate processing resources on a single stimulus or task while actively filtering out competing sensory input.
FlowTask Switching
Task switching is the cognitive process of redirecting attention between tasks, incurring a switch cost that reduces productive time by up to 40 per cent.
FlowTime Blocking
Time-blocking is a scheduling method in which a worker divides the working day into discrete, dedicated chunks of time, each assigned to a specific task or category of work in advance.
FlowYerkes-Dodson Law
The Yerkes-Dodson Law maps the inverted-U between arousal and performance.
