I just got addicted to getting better. My coach gave me a goal to get a tip dunk in a game - you know, a putback dunk off a rebound. I had never done that. He told me that he'd get me a pair of new shoes if I did it. I just kept trying. I couldn't get it, couldn't get it, couldn't get it. It took me a year or so. Finally, one game, I got it.
