Use a 15-minute end-of-day planning buffer to close the day’s loops

Before leaving work, take 15 minutes to list tomorrow’s priorities and explicitly close today’s open loops.

Why it works

Research on work-recovery (Sonnentag & Fritz) shows that psychological detachment from work predicts next-day energy and performance. Zeigarnik loops — unresolved today’s tasks — are a primary barrier to psychological detachment because the brain continues working the problem in the background. A deliberate end-of-day closure practice — writing tomorrow’s plan, declaring today "done" — signals to working memory that the open loops are handled, enabling genuine detachment.

How to do it

1. At the end of the workday, spend 10–15 minutes writing tomorrow’s top 3 priorities.
2. For each open loop from today (unfinished tasks, unanswered questions), record the next step or deliberately defer it with a specific future date.
3. Close your applications and leave the workspace when the review is done.
4. Say explicitly to yourself: "Shutdown complete" — a ritual that signals the brain the day is closed.

Evidence

Sonnentag & Fritz (2007) found that psychological detachment from work during off-hours predicts next-day vigor and performance. Masicampo & Baumeister (2011) showed that planning reduces task intrusion. The end-of-day closure practice applies both mechanisms. (observational)

Detachment research is observational; causation may run in both directions (people who detach may also have lower workloads). The planning effect on intrusion has experimental support.

Common mistake

Writing tomorrow’s plan but then continuing to check email afterward — which reopens Zeigarnik loops immediately after closing them, defeating the detachment function.
