I haven't listened to audio books, but I love podcasts. Of late, I've been listening to The New Yorker's Writers Read podcast, and it's quite great. Certainly, it's a literature podcast, so not much sports-related happening there. But I do love to read psychology texts in relation to sports. I play ultimate, and reading psych helps sometimes. Currently reading Schultz and Schultz's Theories of Personality. Interesting in the context of how much pressure student athletes face: they gotta do well academically, on the field, please parents, teachers, friends, and the school. Not many handle this too well, and understandably so. Doesn't matter whether you're a so-call introvert or extrovert, pressure is pressure. The book deals with, among other things, how therapy can help us overcome pressure and other barriers. Quite interesting.
