There is precious little in civilization to appeal to a yeti.

Motivation is the single most important factor in any sort of success.

I was incredibly stubborn. I mean, I believe that my father was frequently in the right, but I would never admit it, and so we did have a few set-tos on various topics; but on the whole as I got older and my father got more mature we got along reasonably well.

In those days we were punished very frequently and I felt that it was often unjust, and so I would resist the desire to agree with many, many things. So I used to get beaten quite frequently and I more or less accepted it as part of life.

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.

I would have said that during the early days of my life there was never a moment when I wasn't fit. We worked extremely hard on the beekeeping line, and both my brother and I used to compete, particularly when we were collecting honey. We would each have an 80-pound box of honey and we would race up the hill on the Tuakau track and race back down. We just raced all the time, and we used to keep very fit indeed.

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.
