Perhaps one character trait which does help is the ability to focus, and perhaps to be a little stubborn. If I learned something in class that I only partly understood, I wasn't satisfied until I was able to work the whole thing out; it would bother me that the explanation wasn't clicking together like it should. So I'd often spend a lot of time on very simple things until I could understand them backwards and forwards, which really helps when one then moves on to more advanced parts of the subject.

That is true. That one little corner of South Africa, Port Elizabeth and its immediate surroundings, is a region that I know like the back of the hand that holds my pen as I write about it. I can stand on a street corner in Port Elizabeth, look at anybody and put together some sort of biography. I know where they come from, where they’re going. I have a feel of the textures of their life. If I stand on a street corner in New Haven, which is a place I’ve gotten to know as well as any place outside of South Africa, I am still at a total loss to identify the people passing me on that street.

I wanted to be an Olympic champion and I didn't care about the goings-on around me. In my heart and with all of my soul I was ready, willing and I was very able. I had a deadly sense of self-belief. I'd go to another level and say I had a deadly sense of self-conviction where you can say whatever you want, you can do whatever you want but you're not going to touch me.

I like simplicity. To me, this is very, very important, whether I am dealing with science or dealing with people.

That they get it.
