“I realized that I would have some very tough sledding, and I was very discouraged because I didn't see much hope of getting into the field I wanted to get into with no college education.”

“It was depressing, very depressing. I worried about how I would make a living. I didn't want to stay on the farm. It didn't offer the challenge I wanted and yet, without a college education, I felt that I was really out of luck.”

“I think the driving thing was curiosity about the universe. That fascinated me. I didn't think anything about being famous or anything like that, I was just interested in the concepts involved.”

“That's the way I got along in life. I don't ever remember being particularly jealous of anybody, because I figured if I can't do it myself, I don't deserve to get it.”
