"I've been approached several times, but it just didn't feel right. When I'm 80, I want to feel that I helped give access to a world-class education to billions of students around the world. Sounds a lot better than starting a business that educates some subset of the developed world that can pay $19.95/month and eventually selling it to some text book company or something. I already have a beautiful wife, a hilarious son, two hondas and a decent house. What else does a man need?"
