I have a lot of sympathy for young people because I realize how disturbed I was. How would I deal with life in the future? What would I do for a living?

How does a pansy, for example, select the ingredients from soil to get the right colors for the flower? Now there's a great miracle. I think there's a supreme power behind all of this. I see it in nature.

I used to think about how nice it would be to visit the planets. Of course, I didn't expect to see in my lifetime what has happened. I knew it would happen some day, but it came along faster than I at first thought.

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.

A person that much interested in science is going to neglect his social life somewhat, but not completely, because that isn't healthy either. So one has to work it out according to one's own inclinations, how one wants to proportion these things.

I guess they just took it for granted that that was what I was interested in and let nature take its course.

By the time I was in sixth grade I could bound every country in the world from memory.
