CHAPTER 14 — How to Make Good Habits Inevitable and Bad Habits Impossible

Willpower is fragile. A better strategy is to make good habits the default and bad habits difficult to execute.
Use commitment devices: choices you make now that lock in better behavior later. Automate savings. Schedule workouts with penalties for missing. Keep healthy food prepped and visible. Create barriers around temptations—site blockers, limited access, removing payment info, leaving the phone outside the bedroom.
These are not tricks. They are systems that protect you from future moods. When you rely on willpower, you fight the same battle daily. When you rely on structure, you win once and collect the benefit repeatedly. The goal is not to be strong all the time; it’s to be strategic once, so strength is rarely required. Build rails that guide behavior, and you stop depending on motivation to keep you on track.
