Believe me, you're not Bill Gates. If you were, you wouldn't be looking around to see what other people were doing, and mimicking their approach. Being an autodidact is a force-play. You run to second base on a ground ball or you're out. There's no deciding in it. You are or you ain't. Bill Gates and his ilk stole second and third and home, and you're still trying to bunt."
