My worst intellectual habit has to be overanalyzing everything. I do it all the time, because there are too many options in this world.

My half measures are really not good measures.

I’ve a deplorable tendency to become entrenched in my own prejudices: If I dislike an artist, an art form, or an idea (jazz, ballet, certain kinds of fiction) it is extremely difficult to get me to change my mind, and all evidence presented to the contrary will be discarded and very likely mocked. Of course, nobody suffers but me.

But it seems to me that I’m somebody who is deeply skeptical and trying to combat this skepticism. So my writing is probably situated somewhere between the poles of skepticism and ecstasy, with my dream being to have more ecstatic poems.

My wife and I have always tried to explain to the girls — even when I had to go off on nine-month cruises in the Mediterranean or in the Pacific — why I was doing it, and what it was all about, that I felt that I could contribute to the military.

Pretty good, I think. I didn’t mind studying. Obviously math and the physical science subjects interested me more than some of the more artistic subjects, but I think I was a pretty good student. Obviously the teacher thought so.

If it’s one thing, obviously it had to have been being selected to make the first manned space flight for the United States. That was competition at its best, not because of the fame or the recognition that went with it, but because of the fact that America’s best test pilots went through this selection process, down to seven guys, and of those seven, I was the first one to go. That always will be the most satisfying thing for me.

No. I think all of us had such confidence in the technology that it was not a question. It was just a question of scheduling and a question of the funds to do it. I think one has to have that kind of an attitude, particularly when you are involved in research and development. You’ve got to believe it’s going to be done eventually.

I didn’t like it at all. This problem is called Meniere’s syndrome. It causes dizziness, nausea, lack of balance and so on. The prediction was that in some cases it was correctable. I said, “In my case it is going to be correctable.”

Oh, absolutely. I was delighted when I was assigned command of the first Gemini flight with Tom Stafford as my co-pilot, but it was shortly after that I developed a disorientation problem in my ear, and NASA grounded me. I was grounded for almost six years.
