If you are pretty good at following through already, then you are probably using many of the suggestions in this book without realizing it. If you have follow through problems, then this is probably a useful investment. The authors do a very good job of communicating their message clearly with many examples. I would say the book could be summarized by two messages: (1) Each of us has a conflict between our short term desires and long term goals. We would prefer to eat that donut now and yet we worry about the heart attack we might get in 20 years. (2) To resolve these conflicts and achieve our goals, we need to alter our environment (in creative ways) so our desires and goals are aligned. The first message is important because it provides a useful way to understand our failings without piling on a lot of regrets. The second message provides the tools to achieve our goals.
