Gary Mack's book on the importance of your thinking processes in sport (and by extension in life) has two problems. Firstly, if you don't know American sports in the Nineties then many of the names in his anecdotes will be unfamiliar. Secondly, for those who do know American sports in the Nineties some of the teams he has advised are not exactly stellar. But this just means you need to read with care, and if you don't share the inordinate interest with golfers (or cannot avoid the thought that this is just sport, what about life?) you can go straight to the summary points at the end of each chapter. These are annoyingly smug and even more annoyingly they do seem to work.
Mack uses many of the processes of NLP with an helpful dollop of commonsense. So please don't be put off by the anecdotes concerning unknown but obviously revered athletes. He packs much the same message as an Anthony Robbins book but in much less space.
