Motivation is unreliable. You can't trust it. Some days you have it, some days you don't, and you can't control which. But discipline is reliable. Discipline is the decision to do something regardless of how you feel. This book teaches a discipline-first approach to change. You'll learn that the most productive people aren't the most motivated—they're the most disciplined. You'll discover that discipline is a skill, not a personality trait, and like any skill it can be developed. You'll learn that the people who change their lives aren't waiting for inspiration—they're doing the thing they've decided to do, whether inspired or not. You'll find that discipline removes the emotional variability and creates reliable progress. For anyone exhausted by trying to stay motivated, this offers permission: you don't need to feel like it. You just need to do it.
