I don’t believe I can really do without teaching.  The reason is, I have to have something so that when I don’t have any ideas and I’m not getting anywhere I can say to myself, “At least I’m living; at least I’m doing something; I’m making some contribution”—it’s just psychological.

I act like a hopeful person, but I think that hope is based on having zero expectations.

Yeah, there were a lot of brave people who stood up. Then, you know, it cost Martin Luther King and Medgar Evers and the three civil rights workers in Philadelphia, Mississippi, and Viola Liuzza and a lot of the others their lives, but they were on the right side of history, and they believed if they made this sacrifice that it would work out. And whenever I get discouraged about everything they stood against rising up again, I realize there just are no public, or permanent, victories. You have to keep fighting for freedom.

The power of positive thinking.

And I think that still is true of this business — which is basically research and development — that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.

I would say that they have to know deep down inside that it’s something that they really want to do, themselves. It’s not to please mommy or daddy, not to please Uncle Harry because he did this, or daddy did that. It has to be because you know you are qualified to do it, and if you apply yourself, you can do it.

I think all of us certainly believed the statistics, which said that probably 88 percent chance of mission success and maybe 96 percent chance of survival. And we were willing to take those odds.

We always tried to share experiences with them. It was a little more difficult for them after the astronaut business, but they’ve responded well. All three are happily married, with their youngsters. And they’re not just happy homemakers. They’re all involved in little projects of their own, because they are challenged by wanting to help local charities, or wanting to start a business. I think they have turned out reasonably well.

To me and, I think, to all of us, it was a realization that our world is finite, it is small, it is fragile, and we need to start thinking about how to take care of it.

No, I didn’t. Certainly when I was in the one-room country school you described, I guess my ambition at that point was to get through with a creditable performance. Really, of course, nobody thought about astronauts in those days, but I didn’t really even start thinking about airplanes very much when I was in grade school. So that interest sort of came later on.
