He argues that the most damaging time sink isn’t project work itself, but the administrative burden surrounding it (emails, messages, meetings, check-ins). When that overhead crosses what he calls an “excessive overhead threshold,” progress on non-urgent but important priorities becomes very difficult.

He says schedules become unusable when free time is chopped into small, interrupted pieces; what matters is having non-trivially long, undistracted blocks. He recommends adding constraints to prevent meetings and appointments from being scattered randomly across every open slot.

He recommends adding 10–15 minutes at the end of meetings to capture tasks, send follow-ups, schedule deadlines, and close open loops. This reduces mental residue that otherwise distracts you during the next work block (or even the next meeting).

He describes “unscheduled messages that require responses” as a major source of context switching that kills focus. His alternatives include office hours, docket-clearing meetings built around a shared running list, and “process-centric emailing” that defines a workflow upfront to avoid long back-and-forth threads.
