I'm a huge fan of taking things that work for you and leaving the rest. I had commented in a similar thread recently about Max Eberle's Zen Pool. I have found one or two of his chapters interesting and valuable, but as a whole, there was no cohesive philosophy. It was easy to read as every chapter was in bite size chunks.
I am a couple chapters into "Pleasures of Small Motions", and while it's a bit wordy and loquacious, I did enjoy the ideas presented about motivation. I will continue it and see what other nuggets of information I can pull.
Lastly, ElCorazon seems to be a big proponent of the Tennis book. I haven't read this, but it would seem to me that Tennis, Fooseball, and other sports are reaction based. Pool is not. For those of you that read both, do you think this impacts the philosophy behind "Inner Game of Tennis"?
