Slipping back into an old habit for a day isn’t a reset to zero. Just pick up where you left off.

Progress does not sit on a switch that one bad day flips off. The real damage from a slip usually arrives afterwards, when you decide the streak is ruined and may as well stay ruined until Monday. Twenty good days plus one off day is still twenty good days.

Next time you miss, make the following day boringly normal rather than heroic. No making up for it, no starting over. Just the usual version of the thing, at the usual hour.
