Shutdown rituals can become annoying, as they add an extra ten to fifteen minutes to the end of your workday (and sometimes even more), but they’re necessary for reaping the rewards of systematic idleness summarized previously. From my experience, it should take a week or two before the shutdown habit sticks—that is, until your mind trusts your ritual enough to actually begin to release work-related thoughts in the evening. But once it does stick, the ritual will become a permanent fixture in your life—to the point that skipping the routine will fill you with a sense of unease.
