Chapter Summary One of the most satisfying feelings is the feeling of making progress. A habit tracker is a simple way to measure whether you did a habit—like marking an X on a calendar.

Never miss twice. If you miss one day, try to get back on track as quickly as possible. Just because you can measure something doesn’t mean it’s the most important thing.
