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.

People tell me that I work hard. I never feel that I do particularly, because it’s fun. I always say, “Well, I’ve never worked hard in my life.” I’m busy, but most of what I do is enjoyable. It isn’t that it’s not tedious to some people, and so on, and of course I have routine to do, but I don’t mind it. I just don’t feel that I’m put upon. I spend a lot of time, but it’s fun. It’s a very intensive hobby. I would say it’s my most serious hobby. I have lots of hobbies, but the one permanent one is science, physics. So yes, I spend a lot of time, and I would agree with Edison, you have to work very hard and intensively.

It’s best to start writing when you wake up in the morning, or afternoon, or whenever it is you wake up. Just start then, because you are closer to the dream state than at any other time in the day, which means the imagination is really working on all cylinders, and it means that whatever it is that manufactures sentences in your head is very fresh, and you have all kinds of slants on things that by the end of the day you won’t have, or you will just lose along the way. Further advice I have not.

Yes, that’s right. I saw what I could succeed in. I never considered myself very bright, and I always thought of myself as mathematically mediocre. So I figured that probably, like your college runner who has difficulty breaking a ten-second hundred — well, breaking an 11-second, shall we say, 100-meter — realizes that their best shot is to rely less on strength and speed and more on self-discipline, planning, and long hard work. Yes. That’s the way I do science.

The closest to inspiration was my beloved fifth grade teacher, Mrs. Ponti, who I’m delighted lived long enough to get that book’s dedication. I exchanged Christmas cards with her for the rest of her life. She was a wonderful woman. I think the main way she inspired was by respecting students’ interests. She herself knew very little science. Science was not formally taught at all, as far as I can remember, at grade school level. She realized there were a group of us who were interested in science, so she would let us sit by ourselves in the back of the classroom once a week for a couple hours, and she got books for us and discussed science. So I suppose she was a very good model for good students.
