Customer Review

Reviewed in the United States on July 2, 2018
How this book is so popular I don't know. They just state the obvious and come in and fix complex problems with a simple tag line. There's not much to actually apply to specific problems. There are a few concepts here that aren't bad but this could have been a 15 minute power point and I would have gotten the same info.
