Pitching With Purpose - New York Times

A few years ago, a former professional baseball player mentioned a book that had made a great impression on him. It was called "The Mental ABC's of Pitching," by a sports psychologist named H.A. Dorfman. I read the book one spare evening, though, as you may have noticed, I'm not a pitcher — and no major league organization has expressed interest in making me one.

The book left an impression on me too, mostly for its moral tone. Dorfman offers to liberate people from what you might call the tyranny of the scattered mind. He offers to take pitchers, who may be thinking about a thousand and one things up on the mound, and give them mental discipline.
