I am a lucky man. I have had a dream and it has come true, and that is not a thing that happens often to men.

If I'm selecting a group, the first thing I look for is a record of achievement . . . If (candidates achieve) in small things, there's a very good chance they'll perform well in big things.

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.

With practice and focus, you can extend yourself far more than you ever believed possible.

I'm a very, very modest person and with limited abilities. I do have the wish to succeed in anything I undertake, and that does help out, but, in general, there are so many other people who are skilled in their field that I feel very ordinary.

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.
