Once Juni understood a key maxim of Behavior Design—simplicity changes behavior—she refocused her personal efforts to create a constellation of habits, tiny in size but big on impact, that helped her to kick her sugar habit for good.

In Behavior Design, we’ve named this temporary surge in motivation the Motivation Wave. I’m sure you’ve experienced this before: Your motivation crested, then came crashing down. And maybe you blamed yourself for not sustaining it. You’re not to blame. This is how motivation works in our lives.

When we match ourselves with behaviors that we already want to do, not what we think we should do, there is no need to fuss with motivational tricks or techniques later. We take the Motivation Monkey out of commission.

People change best by feeling good, not by feeling bad. Amy set herself up for success by thoughtfully using prompts to design changes. Those changes worked because they helped her do what she already wanted to do. And that success? That felt good.

Success leads to success. But here’s something that may surprise you. The size of the success doesn’t seem to matter very much. When you feel successful at something, even if it’s tiny, your confidence grows quickly, and your motivation increases to do that habit again and perform related behaviors. I call this success momentum. Surprisingly enough, this gets created by the frequency of your successes, not by the size. So with Tiny Habits you are shooting for a bunch of tiny successes done quickly. Not a big one that takes a long time.
