You should, I went through it and found it really useful. The main ideas in the program is to start extremely small then celebrate and consciously practice doing that habit for a few days. The tiny part is literal, he suggests taking the smallest possible unit and making sure it's less than 30 seconds. For instance if the habit was brushing your teeth you would just need to consciously practice brushing one tooth. And then the celebration is equally tiny, such as just saying "awesome" when you consciously do something.

It sounds kind of corny, but it's effective. The idea is to get your brain to automatically associate a new habit with a really tiny action that will instantly give you a reward. So if you wanted to create a habit of brushing your teeth after getting up, you'll do it without much though even thought you only consciously brushed one tooth when you were trying to create the habit.
