Willpower

This came across in my library's e-reader service and looked interesting. But now the only things I remember are that you shouldn't make decisions while hungry, and, at the same time, you shouldn't leave big bowls of M&M's lying around. I did enjoy reading about various celebrities like Drew Carey. However, I was a little disappointed that the focus was not on how he became healthy, but rather on how he conquered his disorganized email and office clutter problem. He did this by hiring David Allen himself, the Getting Things Done guru, to come once a year and organize for him. Which, now that I think about it, doesn't really say much about Drew Carey's willpower...
