Deep Work

Deep work describes sustained, distraction-free concentration on a cognitively demanding task. In this state, working memory and attention are devoted to a single goal, which improves learning, quality and speed.

Depth is fragile: interruptions trigger switch costs and attention residue.
Practical supports include single-tasking, time boxing (e.g., 50–90 minute blocks), clear "done" criteria and boundaries for communication.

Deep work is a practice. The more you do it, the more capacity you build—and the less you need to rely on motivation.
