Larry Winget
and
T. Harv Eker

If you prefer a straight forward to no holds barred kind of information, then pick one of these two authors. Larry seems to me to be the more brash of the two, but Harv doesn't pull any punches either. Sometimes we just need for someone to tell us like it is without all the sugar coating and beating around the bush.

Both books center around a persons mindset. They talk about how to take action for change, stop procrastinating, and change the way you think about things (programming). There are exercises and easy stuff everyone can do to start making improvements in their life.
