I believed I was where I was supposed to be of my career in the space program. When I was a student, my mentor told me I’d make a good research mathematician. I said, ‘What is that?’ and he told me I’d have to find out for myself. At NASA, I happened to be at the right place at the right time. When you put bright people in a room and they had something to do, they worked on it until they got it done. But honestly, it was never work to me.
