"I think I mainly climb mountains because I get a great deal of enjoyment out of it. I never attempt to analyze these things too thoroughly, but I think that all mountaineers do get a great deal of satisfaction out of overcoming some challenge which they think is very difficult for them, or which perhaps may be a little dangerous."
"While on top of Everest, I looked across the valley towards the great peak Makalu and mentally worked out a route about how it could be climbed. It showed me that even though I was standing on top of the world, it wasn't the end of everything. I was still looking beyond to other interesting challenges."
"I think my first thought on reaching the summit- of course, I was very, very pleased to be there, naturally - but my first thought was one of a little bit of surprise. I was a little bit surprised that here I was, Ed Hillary, on top of Mt. Everest. After all, this is the ambition of most mountaineers."
"I'm sure the feeling of fear, as long as you can take advantage of it and not be rendered useless by it, can make you extend yourself beyond what you would regard as your capacity. If you're afraid, the blood seems to flow freely through the veins, and you really do feel a sense of stimulation."
"If I wished to do something, even if I couldn't find anyone who wanted to make the effort with me, I would go out solo climbing. I did find solo climbing very challenging and a little frightening. You knew that you were completely on your own, and you had to overcome all the problems and possible dangers."
