Why seven dots beat a 30 day challenge
A week is short enough to finish and long enough to notice. Here is how we chose the row.
Most habit plans ask for thirty days. Thirty days sounds reasonable in January and impossible by the second week of February. When we looked at how people used early versions of Dotty, the pattern was clear: people who thought in weeks kept going, and people who thought in months stopped.
A week is a unit you already live in
You know what your Tuesdays look like. You know which evening is always late. A row of seven dots maps onto a rhythm you already have, so planning takes no effort. A month has no such shape.
A row you can finish by Sunday is worth more than a challenge you abandon on day eleven.
Finishing is the reward
A full row is a small, complete thing. You get that feeling fifty-two times a year, compared with twelve for a monthly goal. We tested rows of five, seven and ten dots. Seven had the highest share of people starting the next row.
What to do with a broken row
Leave it. An empty dot is information, and it tells you which day needs a different plan. Next week starts a new row whatever happened in this one.
