If you are expecting substantive theoretical sports psychological insights from this book, you will be thoroughly disappointed. While the anecdotes presented by the author are amusing, they provide little to no substance. Often, they are redundant to the point where it seems the author is beating the stain where the dead horse used to be. Each chapter ends with a short 1-sentence summary. In my opinion, the book could easily be condensed to only the chapter headings and the 1-sentence summaries, although it would be much less entertaining that way. The 1-liners do contain good information, but, unfortunately, much of it is what I would consider common sense.
Unless you can relate to baseball and other American sports, don't bother picking up this book. Most of the anecdotes are from the world of baseball.
That said, the book is a very easy read. I do not question the author's abilities as a sports psychologist. But I had expected a book with much more substance.
