" Furthermore, the world is so complex, and fate so uncertain, that you can never really control other people or the environment effectively enough to be master of your own destiny. Reason is not powerful enough to build intellectual systems or models to allow you to accurately understand the world around you or anticipate what is to come. Your willpower is not strong enough to successfully police your desires. If you really did have that kind of power, then New Year’s resolutions would work. Diets would work. The bookstores wouldn’t be full of self-help books. You’d need just one and that would do the trick. You’d follow its advice, solve the problems of living, and the rest of the genre would become obsolete. The existence of more and more self-help books is proof that they rarely work. "
