I find that you’re a completely different person as a maker than you are as a listener. That’s one of the reasons I so often leave the studio to listen to things. A lot of people never leave the studio when they’re making something, so they’re always in that maker mode, screwdriving things in - adding, adding, adding. Because it seems like the right thing to be doing in that room. But it’s when you come out that you start to hear what you like.

Well, yes, no, I certainly visualise … it was really … I had to have a very good idea of the geometry – that was crucial. Spacetime geometry so it's not three dimensions, you have to think of the whole four dimensional spacetime, and I get sort of used to thinking about four dimensions and using various tricks to get the picture properly. I do most of my thinking in visual terms, and I'm a very visual thinker rather than writing down equations.

When I have a lot of pain, I try to confuse my mind to forget about the pain and think about the distance. I don't want pain to be in my mind, because I'd really lose focus on running. After winning, you won't have that pain, but it comes later. The marathon is hard; the second day, you don't go up or down stairs.

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.

I think motivation is the single most important factor in any sort of success. Physical fitness is important, technical skill is important, and maybe even the desire for money is important in some respects. But a sort of basic motivation, the desire to succeed, to stretch yourself to the utmost is the most important factor. Certainly in the field of exploration and activity, it’s the thing that makes the difference between someone who does really well and someone who doesn’t.

I think most of our major challenges are not going to be in the physical field at all. I think they’re going to be in the field of human relations, of getting on with each other, of contributing. People accepting that they have to contribute something, their thoughts, their ideas, maybe even their money, towards producing a world society that is perhaps a little bit more honest and reasonable than it is now.

The press and the public have created an image of Ed Hillary, hero and explorer which simply doesn’t exist. They’ve painted a picture of me as a heroic type, full of enormous courage, tremendous strength, undying enthusiasm and all the rest of it. But it’s all really just a story, that’s been written up in the newspapers. I’m a person, as I’ve said, of modest abilities, with a good deal of determination, and I do quite a lot of planning ahead. With careful planning and good motivation, I think you can often achieve things that other much more talented people would probably do much more easily.

I still regard adventure pretty much as a hobby to tell you the honest truth, and I think this approach to it keeps one refreshed almost. I think if you just regard adventure as a business, working becomes very boring as many other businesses can become. But even though adventure changed my life considerably, both in what I was doing and even economically, I’ve always regarded myself in a sense as a competent amateur.

In the first 33 years of my life which is up until I climbed Everest, I was a very restless and slightly unhappy sort of person. I really didn’t have a great deal of social life, but I’d become very interested in adventurous activities. Perhaps, I was, in some respects something of a loner. But after I got married, that certainly changed my life very considerably, indeed. I found that it was possible to mix having a family with continuing on with adventurous activities, but I think a great deal of that was having a suitable wife. My wife was very, long-suffering. She knew that there were certain things I wanted to do and she was happy that I should do them. She was prepared to put up with considerable periods of being alone with the kids. She, was marvelous, so it made it possible for me to do the things that I wanted to do as well.

I would advise them to aim high. To set their sights at a pretty tough target and don’t be too worried if you’re not successful at first. Just keep persisting and keep improving your standards, getting better and better and ultimately, you’ve got a pretty fair chance at achieving your desired goal. ... But, I do think that virtually everybody that’s born has the ability to be very competent at doing something. I think that, in itself, is worthy of aiming towards, just to be competent at doing anything you particularly wish to do.
