Query: Rah Rah, not How-to

Professor Peters is/was a Harvard professor of business who concentrated on researching and teaching competitiveness. I liked his serious books and text books. He's a really high energy speaker and has a quite lucrative business in coaching. Therefore, I should not be surprised that this little book is full of gimicky fonts, colors, buzz words... and is closely associated to the sales-oriented web site of the same name. Maybe there's good content there, but the presentation screams: motivational, not content-rich. And that's what I think the book is good for.
