 He was the five-time teacher of the year in New York, and he became totally disillusioned when he realized that the purpose of being a school teacher was not to teach math. I think that maybe he taught English, English or math. He said, I became disillusioned the day I realized my job was not to teach math, but my job was to teach school. Think about it. In school, they teach you that nothing is important. How do you do that? It's the only place that you will ever work in your life where you work on something for 45 or 55 minutes, and then a bell rings, and you close your book. You don't care about that anymore until tomorrow.
