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

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

I think my strengths perhaps are that I'm determined. I may not be the best climber in the world, but I do like to sort of succeed and so that tends to drive me on, as it were, and I don't give up too easily.

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 get older I get more cantankerous, but June [Hillary] gets a bit more cantankerous, too.
