One of the best ways to strengthen our independent will is to make and keep promises. Each time we do, we make deposits in our Personal Integrity Account. This is a metaphor that describes the amount of trust we have in ourselves, in our ability to walk our talk. It’s important to start small. Make and keep a promise—even if it means you’re going to get up in the morning a little earlier and exercise. Even if it means you aren’t going to watch television tonight. Even if it means you’re going to subordinate taste to nutrition for a week.
