Query: Good start, fails in the second half

Although this book started out with some great ideas, by the middle I was tired of the self-promoting and sappy style. In fact, I could not read the second half at all. I tried to ignore the writing style and get to the meat, but the book was ruined by too many personal stories and pontification when I was looking for straightforward, solid business practices. Some of the basics are there, but they are hidden in a sea of mush.
