Although this book is geared towards pool players, anyone playing a sport or just navigating life will find this useful. It's all about mentally mastering the game, whether that's pool or life.
The best advice I gleaned was the old adage, practice, practice, practice. By practicing, we turn the conscious into the unconscious; our bodies take over and do the hard work without us fretting about it in the midst of competition or stress.
It is important to find other facets to enjoy such as comaraderie, mentorship, distraction from life.
Author Bob Fancher contradicts lots of popular advice, one being "don't think about it" (it being various things like the score, your competitor, etc.) Instead, he advises *do* think about it. Think about it and then focus on your remedy, whether that's enjoying the game, revving yourself up, or calming yourself down.
If you find yourself with an impossible to reach goal, then switch goals. It's all about being realistic.
