Query: Good, but not good enough

I think of this book as something of a case study. However, it's not really written like a case study. It's written as a stand alone book. For that, I give this book only 2 stars. The E-Myth Revisited was an excellent book. Exceedingly worthwhile to read. This one was not. I could have done without it and, probably, so can you.
