WillpowerPosted: August 17, 2012
Baumeister and Tierney are researchers, and they’ve done countless studies of their own; the book also draws on studies done by other researchers to give convincing evidence in favor of their conclusions. Of course, that could just mean the authors are skilled writers.
The point of the book is that it takes energy to exercise willpower; you need to eat the right kinds of foods to give your brain the necessary fuel; willpower can be strengthened by frequent use. Most importantly, developing small habits (like shaving every morning or having good posture) strengthens your willpower, and it will be easier to have self-control in other areas of your life.
Basically, think of willpower like a muscle. Be strong!
