But I couldn’t let myself feel that way until it was all right to. And that’s part of the surgical mind too, addressing what you need to, and you know you can do, and postponing how you feel about it, thinking only of the patient and what you need to do.

The look of the thing is one thing. The sound of it is more important. … When you write a play, it makes a certain kind of noise in your head, and for me rehearsals are largely a process of trying to reproduce that noise. It is not always wise to reproduce it in every instance, but that’s another question.

Curiosity is a form of humility — acknowledging that you don't know everything. Responding to curiosity allows other people to speak freely. Facts and details matter and inform a deeper and deeper analysis that allows you to continually revise and update your plans. This, of course, also means that you are constantly admitting prior mistakes. You need to shed sacred cows, seek out blind spots and challenge the status quo.

My most important rule is one that sums up the 10: if it sounds like writing, I rewrite it.

I had one experience on the ice-fall with Tenzing. We were actually descending after having been further up the mountain, and it was getting close towards dark so we wanted to get through the ice-fall before darkness fell. We were roped together, but I was rushing down ahead in the lead. About halfway down there was a narrow crevasse. I guess it was about four feet wide, but just a bit too wide to step across. On the lower lip was a great chunk of ice stuck against the ice wall, and we’d used that as sort of a stepping stone to get over the gap. I came rushing down the hill without thinking too carefully. I just leapt in the air and landed on the chunk of ice, whereupon the chunk of ice broke off and dropped into the crevasse with me on top of it. It was interesting how everything seemed to start going slowly, even though I was free-falling into the crevasse. My mind, obviously, was working very quickly indeed. The great chunk of ice started tipping over and I realized, if I wasn’t careful, I’d be crushed between the ice and the wall of the crevasse. So I just sort of bent my knees and leapt in the air. I was still falling, but now I was a couple of feet clear of the chunk of ice. Time really seemed to pass even though I was falling clear, and I realized that unless the rope came tight fairly soon, I would come to a rather sticky end on the bottom of the crevasse. Up top, Tenzing had acted very quickly. He had thrust his ice axe into the snow, whipped the rope around it, and the rope came tight with a twang, and I was stopped and swung in against the ice wall. The great chunk of ice just carried on and smashed to smithereens at the bottom of the crevasse. Then really the rest was what I would have called a routine mountaineering matter. I had my ice axe and my crampons on my feet, so I chipped steps in the side. I was able to bridge the crevasse, and I worked my way up to the top and got safely out. I wouldn’t have said at any stage, because it all happened so quickly, fear really didn’t have much opportunity to emerge. My only idea was to get safely out of this unfortunate predicament. And of course, without Tenzing’s very competent mountaineer’s response, I certainly wouldn’t have made it. But once he had stopped me, then I was able to, using the techniques of mountaineering, to get myself safely to the top again.

As I’ve gotten older, my goals have become more solidified. My main concentration is on the welfare of the people I’ve worked with in the Himalayas and on human welfare in general. I’m also extremely interested in the environment and trying to encourage people to be more concerned about what we’re doing to our world. Now I’m just one of thousands and thousands of people who have these same views these days. I think this is one of the great steps forward we’ve seen in modern decades — the considerable growing interest that people have in the environment and in keeping it reasonably clean and wholesome. I certainly hope it remains that way.

Well, then of course, came the disaster in 1975, when my wife and my youngest daughter were flying into the Nepal hills where I was building a hospital and their plane crashed and they were killed. And this certainly, for me, was an absolute disaster, really because the two people that meant most to me in life had been killed in one fell swoop. It did take me quite a number of years to get over it. I found the only way to deal with it was to carry on very energetically, doing the things that we had all been doing together, which was largely building schools and things for the mountain people. Although, people used to say to me, “Time is the great healer,” certainly for the first two years I simply didn’t accept this. But, time was a great healer and after the years passed, the memories still remain. But, I think quite a lot of the pain tends to fade a little bit, and life did become a little bit easier.

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 personally wouldn’t be, if I could possibly help it, involved in a serious pursuit in which there weren’t a few people who could laugh a bit about it. Because I can remember many occasions — maybe we’ve been stuck in a tent or we’re up on the side of a mountain, this heavy snow, avalanches all around us, and we can’t get up and we can’t get down, but we just sat in the tent and reminisced about occasions and days gone by and laughed about old jokes and all the rest of it. Then you really have a very good time, even though you’re sort of poised there between disaster both up and down. People who can make you laugh under those circumstances are very valuable indeed in an expedition.

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.
