The title of this book caught my attention at the library as a golf book I hadn't read. The idea of purposeful practice is not new but the authors attempted to put a different spin on the topic. In the end, the whole book could have been presented in a one page handout. Many concepts were repeated several times. Most people don't have the time to practice and do all the drills that were suggested. Perhaps if one were considering a career in golf it would be helpful but that doesn't apply even to avid amateur golfers. In fifty plus years of golf, I have learned most of what was presented. The value of the book for me was that it affirmed many of the things that I was already doing.
