Deep work is the ability to focus without distraction on a cognitively demanding task — and in an age of notifications it is becoming a rare, valuable skill. The encouraging science is that attention is trainable: regular undistracted sessions measurably lengthen your focus span over weeks, the way weights lengthen muscle. The discouraging science is that every interruption costs minutes of rebuild, not seconds. This guide is the training plan: environment, sessions, and the recovery that makes the next day's depth possible.
