Experiment setup
Keep it small
For 7 days, make each promise one small thing — a short sentence.
Duration
7 days, starting today.
What we’re testing
Whether smaller promises are easier for you to keep.
How a day counts
A day counts when the promise is 40 characters or fewer, about one short sentence.
How it’s judged
Against your own last 4 weeks, not anyone else’s. A week is a small test, so the result says “promising”, never “proven”.
