I started studying law, but this I could stand just for one semester. I couldn't stand more. Then I studied languages and literature for two years. After two years I passed an examination with the result I have a teaching certificate for Latin and Hungarian for the lower classes of the gymnasium, for kids from 10 to 14. I never made use of this teaching certificate. And then I came to philosophy, physics, and mathematics. In fact, I came to mathematics indirectly. I was really more interested in physics and philosophy and thought about those. It is a little shortened but not quite wrong to say: I thought I am not good enough for physics and I am too good for philosophy. Mathematics is in between.

When I was in elementary school we weren't allowed to do sports other than cheerleading. By junior high they let us play but we had to come back after 6:30 p.m. to practice because there was only one gymnasium and the boys used it first.

The world is the great gymnasium where we come to make ourselves strong.
