The Sherpas play a very important role in most mountaineering expeditions, and in fact many of them lead along the ridges and up to the summit.

We had so much in common [with June Hillary] that we just carried on with life as we had been doing. It wasn't easy, but it was - I realise now that it was the only thing to do.

No one remembers who climbed Mount Everest the second time.

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

On the summit of Everest, I had a feeling of great satisfaction to be first there.

I think it all comes down to motivation. If you really want to do something, you will work hard for it.

I really haven't liked the commercialization of mountaineering, particularly of Mt. Everest. By paying $65,000, you can be conducted to the summit by a couple of good guides.
