Deep Work & Sustainable Focus for Creators

How modern knowledge workers eliminate context switching, structure 90-minute hyperfocus blocks, and preserve cognitive energy in an always-connected era.

Focus is usually treated as a discipline problem. Julian treats it as a scheduling problem, on the grounds that most people concentrate perfectly well when nothing is allowed to interrupt them.

The core of the guide is a 90-minute block: how to choose the one task that goes in it, how to close the loop on everything that would otherwise pull you out, and what to do in the twenty minutes afterwards so the next block is still possible. Context switching is quantified rather than complained about, using timing data from a working week.

Later sections deal with the parts that are harder to control. Shared calendars, teams in other time zones, and work that genuinely does require being reachable. The advice is practical rather than absolute, and includes what to give up when a full block is not available.
