I'm sure the feeling of fear, as long as you can take advantage of it and not be rendered useless by it, can make you extend yourself beyond what you would regard as your capacity. If you're afraid, the blood seems to flow freely through the veins, and you really do feel a sense of stimulation.

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.

I think that a good mountaineer is usually a sensible mountaineer.

I have been seriously afraid at times but have used my fear as a stimulating factor rather than allowing it to paralyse me. My abilities have not been outstanding, but I have had sufficient strength and determination to meet my challenges and have usually managed to succeed with them.

I have the challenges sort of already there and as a consequence my companions feel a considerable desire to do this, too, and they feel very put out if they are left in the cold, so there we have it. We have me who has lots of ideas and then we have a very good team who wish - who are persuaded almost - to take part in these challenges.

I never talk about being leaders and all the rest of it. I can only remember one or two occasions in my life when I actually issued orders, and I felt thoroughly miserable after doing it.

George Lowe was the one who opened the mail, and George started laughing uproariously and I looked up at him in astonishment and said, "What's so funny?" And he said, "You've been given a title", and I said, "Ha, ha, big joke." I didn't believe him but, sure enough, in this letter it indicated that the Queen had given me a title.
