But I wanted to be an entrepreneur, so I didn't. But it has always been my dream to actually teach something. So I said, "What if I just ask and teach a college class?" I lived in Austin at the time, so I went to University of Texas at Austin and knocked on professors' doors and said, "Can I teach your class?" I didn't get anywhere the first couple of times. But because I didn't run — I kept doing it — and on the third try the professor was very impressed. He was like, "No one has done this before." And I came in prepared with powerpoints and my lesson. He said, "Wow, I can use this. Why don't you come back in two months? I'll fit you in my curriculum." And two months later I was teaching a class.
