Sounds like a good book and that's cool that Brad is responding here. I wanted to mention that Brad is making the audio for this book available through LearnOutLoud if anyone wants to listen, rather than read, this book. Here's the link:
Life on Purpose on Audio
It's funny because I was just about to go to Amazon and buy the book and was bummed there wasn't an audio version. Didn't even realize Brad had already uploaded it to our site!
