some of the most noteworthy books I’ve read I guess, like A People’s History of the US, the Howard Zinn book totally changed the way I look at politics. And then in the same way I read a book recently called Sacred Economics that like totally changed the way I looked at economics.

I fell in love with the stories by William Beebe, who was an ocean explorer. He discussed what it was like to go down inside a submersible, and peer out of a port hole and see beautiful, luminescent fish, with lights down the side like ocean liners. Bizarre creatures of the sort that you just don’t see walking down the street, or going into the forest, or even looking around in shallow water.

I believe that I had something called epigenetic imprinting, which I actually read about in a book called The Female Brain by Louann Brizendine. Not to self-promote too much, but I loved it so much I wrote a movie with a brilliant comedian named Neil Brennan and made the move this year. That’s how profoundly it changed my life, because I believe that the more we know about our neural brain wiring, the more freedom we have and the more patience we have with ourselves.

I’d been introduced to Freud through all this because I couldn’t understand why is it so difficult to be brave. There was something inside me that wanted to collaborate all the time with the people who wanted to destroy me, and I was searching for it, and I found there was a thing called the unconscious that everybody has. And you’ve got to be in touch with the unconscious to understand a lot of your behavior. And I read through volume after volume after volume of the collected works of Sigmund Freud.

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 it was a combination of feeling and judgment. I happened to be that sort of person that enjoyed making out plans, but I also enjoy changing plans. On an expedition, although I may start out with a detailed plan, I’m prepared to change it at any moment and completely redo it. So our expeditions turned out to be very adaptable ones. We achieved the final objectives just the same as many other expeditions, but maybe we had more fun in the process because it seemed something we could vary. We still carried on to achieve our major objectives.

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.

Those years from 1953 to 1975 were extremely happy years for me. I did many adventurous activities. I got deeply involved in these aid programs for the people of the Himalayas. I had a nice family, we took our family into the out-of-doors, we camped and we swam and we clambered around the hills. For me, it was a very full and a very happy existence.

I really had no idea whatsoever. I feel that my life developed as I went along. I was never one of those people who, at an early age, had picked an objective and worked steadily towards it. All I knew was that I wanted to get involved in adventurous activity. I didn’t have any specific type of activity in mind, but I wanted to do things that were exciting and adventurous. I had a fairly diffused feeling as to what precisely it should be.

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.
