Willpower isn’t just a skill. It’s a muscle, like the muscles in your arms or legs, and it gets tired as it works harder, so there’s less power left over for other things.

When people have a willpower failure, it's because they haven't anticipated a situation that's going to come along.

Most of the choices we make each day may feel like the products of well-considered decision making, but they’re not. They’re habits.

Self-discipline has a bigger effect on academic performance than does intellectual talent.

If you dress a new something in old habits, it’s easier for the public to accept it.

A movement starts because of the social habits of friendship and the strong ties between close acquaintances. It grows because of the habits of a community, and the weak ties that hold neighborhoods and clans together. And it endures because a movement's leaders give participants new habits that create a fresh sense of identity and a feeling of ownership.
