Challenge is what makes men. It will be the end when men stop looking for new challenges.

Once I've decided to do something, I do usually try to carry it through to fruition.

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 did have my moments of despair. It was certainly not - it's not an experience I would like to have again. And then June came along.

I had a very strong desire to carry out adventures, but in those early days I didn't actually do any. I just dreamt about it.

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.
