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.

Motivation is often unreliable when it comes to home improvement. And it’s also unreliable with diets, exercise routines, creative projects, filing taxes, opening businesses, searching for jobs, planning conferences—selfimprovement of all types. The Motivation Monkey’s traps are stealthy and numerous. They catch you whether you’re facing a big project or attempting to change your habits.

Here’s the unfortunate thing—most people believe motivation is the true engine of behavior change. Words like “rewards” and “incentives” get thrown around with such regularity that most people think you can create whatever habits you want if you find the right carrot to dangle in front of yourself. This kind of thinking is understandable, but it also happens to be wrong.

Yes, motivation is one of three elements that drives behavior. The problem is that motivation is often fickle, and this chapter digs deeper into the challenges it presents.

Behavior Design recognizes this reality: A key to lasting change is matching yourself with behaviors that you want to do. In your quest to exercise daily, for example, you’ll find plenty of options. If streaming Beyoncé and dancing for five minutes while you make breakfast is the exercise you want to do, then make dancing a daily habit. And forget about the treadmill at the gym.

The feeling of success is a powerful catalyst for change. Your confidence grows when you celebrate not only because you are now a habit-creating machine but also because you are getting better and better at being nice to yourself. You start looking for opportunities to celebrate yourself instead of berating yourself.

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.
