A writer is no different than a bricklayer or a bus driver in that sense. You must have discipline. Oscar Wilde said that writing is 10 percent genius, 90 percent discipline. You must have discipline for writing. It is not an easy task. It is very lonely. You’re all alone. You are not in company. You are not enjoying yourself in that sense. You are enjoying yourself in another sense. You are delving into your depths, but you are profoundly lonely. It is one of the loneliest careers in the world. In the theater, you are with companions, with directors, actors. In film. In an office. In writing, you are alone. That takes a lot of strength and a lot of will to do it. You must really be in love with what you’re doing to tolerate the huge loneliness of writing.

No, never. Strangely enough, being such a tomboy, and being so—as my mother says—spoiled as a child, once I started dancing and in a way growing up, I was not the spoiled brat or the rebellious child that I was when I really had no reason to be as a child. When you work, it’s a laboratory. The dance studio, when we were working together, was the place where you experiment. I’m not intimidated by failure or making a mistake, because you learn from those situations. You don’t learn from a situation where you do something well. You enjoy it and you give yourself credit, but you don’t really learn from that. You learn from trial and error, trial and error, all the time. When you fail, maybe you failed in that particular instance, but you have discovered something else. A lot of the ballets that we went on to do were built around mistakes that we had made in the classroom. So you never throw anything out. Rebelling takes up energy. As a dancer, you don’t have that kind of energy to throw away.

It takes a combination of ways to do these things, more than discipline. It’s a way of life. It’s like diet or gymnastics. You can know all the gymnastic things, all the exercises. You can know all the diets, but if you don’t do the diets, if you don’t do the exercise, it won’t work. It’s the same if you have some rules, but you don’t live them. It doesn’t work.

Well, I hate the word, but it’s true that something sometimes visits and other times doesn’t. I wish I felt otherwise, but I feel as though there has to be some catalyst, some inspiration. All of a sudden there’s a phrase in your head. Where does that thing come from? I don’t know, and because I don’t know, I don’t know how to have more of them.

Most scientists do. Of course there are the classical figures. I might talk about Einstein a little bit, for example. Now, when I was in college, I was taking my second course in physics, I remember very well, and it had a chapter on relativity. And I took this relativity on a vacation in the mountains; my family went with me. And I remember very well sitting on a rock up in the hills there overlooking a stream, reading this relativity derivation. And it was just very exciting and interesting. It was a strange new world, relativity. I even thought I had found where Einstein made a mistake. And I went back for lunch, and I thought about it, came back. And I said, “No, he was right after all,” but it was still very exciting. To see a completely different kind of idea and world from what one’s normal intuition shows. Of course, Einstein was one of the great scientists; I’ve always admired him. I fortunately had a chance to talk with him and interact with him a little bit as well.

I suppose it’s easy to say, and it may be true, that my role in the development of the laser is perhaps the most important to society. Certainly in terms of applications, and the direct effects on humans, that has been quite important. On the other hand, there are other things which most people don’t know about, and in the scientific area, that I could argue are really quite important, the discoveries there.
