The difference between the university graduate and the autodidact lies not so much in the extent of knowledge as in the extent of vitality and self-confidence.
I have two Ph.D’s (Mathematics and Quantum Mechanics.) I love both math and physics. But I would be a horrible teacher, because I have no patience with people who are slow to learn, and I didn’t think I would get an opportunity to work theoretically. So, my career is that of a watercolour artist. Which I also love. All’s well that ends well, as Shakespeare told us.
