This may be one of the most important books I read this year. It is a very helpful method to implement good habits and to get rid of bad ones. It explains why many of my goals and ambitions failed in the past, and why motivation by itself is not enough. I have already acquired a number of new habits by following the guidelines in this book. Highly recommended, I’ll probably have to reread it often in the future to keep reminding myself how to make positive changes.
