Personal Development Books

I created a list of my favorite personal development books on Sources of Insight.   I'm a fan of continuous learning with an emphasis on personal excellence.  This includes working on interpersonal skills, leadership skills, thinking skills ... etc.  Basically, I'm on a quest for the best principles, patterns, and practices for effectiveness and books end up being one of my primary sources.  To find the best books, I ask the smartest people I know what their favorite book is that had an impact on their life.  It leads me to some interesting discoveries and down some fun paths.

What's your favorite book that changed your life?
