The strongest streak is not perfect; it recovers quickly.

Perfect streaks end, and the way people respond to that ending decides everything. Treating one missed day as a broken commitment usually leads to missing the next four. Treating it as an ordinary gap and returning immediately preserves the whole thing, which is why quick recovery matters more than an unbroken record.

Decide now what you will do after a missed day, before it happens. The rule can simply be that you return the next day without commentary. That single decision protects more practices than any amount of resolve.
