I like to think of Everest as a great mountaineering challenge, and when you've got people just streaming up the mountain - well, many of them are just climbing it to get their name in the paper, really.

Boredom has always been a problem.

Environmental problems are really social problems anyway. They begin with people as the cause and end with people as the victims

I'm past carrying out some of the wishes that I would have wanted to do before, but I still dream about what I would like to do if I was able to do so.

It's not the moutain we conquer but ourselves.

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.

No one remembers who climbed Mount Everest the second time.
