The 30 day experiment

This project turns the whole subject into one live experiment. You will pick a single habit from the lessons, design the smallest version of it you can honestly run every day, keep a daily record for 30 days, and write up what actually happened. You are marked on the realism of the design and the honesty of the reporting, not on whether the habit stuck, because a truthful record of a habit that fell apart in week two teaches more than a polished story that never happened.

Choose a habit

• A sleep habit: a consistent lights out time, or the phone charging outside the bedroom.
• A movement habit: a daily walk, stretch or short workout, sized so it survives your worst day.
• A phone habit: a notification cull, a no phone zone, or a set time the scrolling stops.
• A mind habit: a short daily gratitude note, or a one line journal of the day's best moment, written before bed.

Design it small, record it honestly

The smallest honest version is the size the lessons kept coming back to: small enough that you can do it on a bad day, real enough that doing it counts for something. Two minutes of stretching is a habit, and an hour of planned exercise you never start is not. Your daily record can be a single line: did it happen, and one word about how it felt. When you miss a day, write that down too, along with what got in the way, because the misses are where the interesting data lives. At the end, write up what happened using the ideas from the lessons: where the friction was, what the trigger turned out to be, whether the never miss twice rule held, and what you would design differently for the next 30 days.
