I was certainly seriously emotionally affected [ when Louise Hillary and Belinda Hillary died], but we were building the hospital at the time and I decided that the only thing to do was to carry on and complete the hospital - and it was a jolly good hospital too, I might say. So I really did it by working and working on the things that Louise and I had been working on.

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.

It is not the mountain we conquer, but ourselves.

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

On the summit of Everest, I had a feeling of great satisfaction to be first there.

There are lots and lots of challenges that I wished - at the time - that I had done.There are lots of occasions where there were exciting things to be done but for some reason or another it was physically impossible for us to do them. I still wouldn't mind if I was able to go down into this most impressive valley in the Antarctic, but of course those things are beyond me now.

I don't spend a lot of time thinking about dying, but I like to think that I've - if it did occur - that I would die peacefully and not make too much of a fuss about it.
