End deep work sessions with a 2-5 minute shutdown ritual…

End every deep work session with a 2-5 minute shutdown ritual that reviews accomplishments, documents next steps, and closes all open cognitive loops before transitioning to other activities.

When This Fires

  • At the end of every planned deep work session
  • When transitioning from focused work to meetings or collaborative work
  • At the end of the workday before personal time
  • Any time you're leaving a cognitively demanding task for a different activity

Common Failure Mode

Skipping the shutdown because "I'll just pick up where I left off." You won't — not cleanly. Tomorrow you'll spend 15 minutes re-loading context that a 2-minute shutdown note would have preserved. Worse, the open loops from today will degrade your sleep quality and personal time because your brain never received the signal that work is done.

The Protocol

In the last 2-5 minutes of each deep work session: (1) Review — scan what you accomplished. Write one sentence: "Today I [completed X / made progress on Y]." (2) Document — write your ready-to-resume note (see Write a one-minute ready-to-resume note before every task…): where you stopped, what's unresolved, next concrete action. (3) Close — review any open tasks or threads. For each, either capture a next action or note "no action needed until [date]." (4) Say (aloud or mentally): "Shutdown complete." The verbal cue signals to your brain that work is over.
