We shared a philosophy together [with June Hillary]. We believed very strongly in the welfare of helping other people, particularly the Third World people.

Nothing can replace courage, a resounding motivation and that little bit of luck.

You don't have to be a hero to accomplish great things---to compete. You can just be an ordinary chap, sufficiently motivated to reach challenging goals.

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 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.

There are lots and lots of challenges that I wished - at the time - that I had done.There are lots of occasions where there were exciting things to be done but for some reason or another it was physically impossible for us to do them. I still wouldn't mind if I was able to go down into this most impressive valley in the Antarctic, but of course those things are beyond me now.

Strong motivation is the most important factor in getting you to the top
