Motivation is the single most important factor in any sort of success.

When I was 50 years old, I actually decided to draw up a list of half a dozen things that I really hadn't done very well, and I was going to make efforts to improve. One of them was skiing, and I really did become a very much better skier.

I would like to be remembered for the schools and hospitals and bridges and all the other activities that we did with the Sherpas. Unquestionably, they are the things I feel that were the most worthwhile of everything I was involved in.

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.

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.

I found fear stimulating. Particularly after you've done something that you'd been frightened of at the time, but you carried through and did the job.

I would have said that during the early days of my life there was never a moment when I wasn't fit. We worked extremely hard on the beekeeping line, and both my brother and I used to compete, particularly when we were collecting honey. We would each have an 80-pound box of honey and we would race up the hill on the Tuakau track and race back down. We just raced all the time, and we used to keep very fit indeed.
