Every year, millions of people set goals: to lose weight, start a business, save money, or become happier. For a few days—or maybe a few weeks—the fire burns bright. They go to the gym, wake up early, eat clean, and work hard. But sooner or later, the fire dims. Excuses creep in. Life gets busy. Old habits return.

The problem isn’t that people lack motivation. The problem is that motivation was never the answer in the first place. The truth is this: motivation is a mood, but discipline is a decision.

Motivation whispers, “I’ll do it when I feel like it.” Discipline declares, “I’ll do it no matter how I feel.”

This book is about that difference.
