Attention is the most valuable resource you own — and the one most under attack. This guide explains why focus is hard, the science behind it, and a practical system to master deep work.
Modern apps are engineered to interrupt you; every switch leaves attention residue that degrades the next task. The guide covers the top-down and bottom-up attention systems, ultradian energy rhythms, and how cheap dopamine makes deep work feel unrewarding.
The Pomodoro Technique, Cal Newport's deep work, time blocking, engineering flow states, the 2-hour study method, and spaced repetition with the Feynman technique — how each works and when to use it.
Sleep, movement, single-tasking and environment design as the foundation; a sample deep-work day; and how to measure depth with a Focus Score instead of vanity hours.
