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

I started to become more active and when I was at Auckland Grammar I went for the first time to the mountains. I went to Ruapehu and for the first time I saw snow. I had never seen snow before and for 10 days the group of us had a marvellous time.

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

My most important projects have been the building and maintaining of schools and medical clinics for my dear friends in the Himalaya and helping restore their beautiful monasteries, too.

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.

I always refused to give in if there was some argument with my father. Whether it was true or not, I refused to admit it and so often I would - well, tell lies, perhaps. I would either do that or change the story. Particularly if I felt that my father was being unjust, then I was very strongly motivated to not accept his ruling.

I think global warming is a very real problem for our world. I've seen the changes that have taken place in the Antarctic, in the Himalayas, where the natural ice has sort of faded away, and there's no doubt in my mind that we're living in a strange world, a world which is not easy to understand or handle, But there's nothing you can do about, you just have to live your life as best you can.
