Consistency becomes easier when restarting is not dramatized.

Restarting only feels heavy when you have made it into a significant event, complete with a reckoning about why you stopped and a resolution about how this time will be different. All that weight makes restarting something you postpone. Undramatic returns cost nothing, so you make them often.

Strip the ceremony out. No fresh start, no new plan, no accounting for the gap. Just the next small session, today, treated as unremarkable. The ordinariness is what makes it sustainable.
