I'm more confident now than I've ever been. As you get older, you have to be.

I grew up in the New Zealand countryside. We didn't have television until I was 14, so sing-alongs were our only entertainment.

My children are my children. There's no doubt about that at all. They're very strong towards me, very protective, and I towards them. It works both ways.

When I'm alone at home, I really prefer to listen to Wagner's orchestral music rather than any vocal music. I find it illuminating not to have to pay attention to voices in the recordings.

That's been my sort of aim in life, to never miss an opportunity.

My energy is undiminished. Someone said to me the other day, 'Are you retired?' and I said, 'Well, I'm just trying to prove that I'm not.' There's so many things to do.

I really believe I've been a good person. Not perfect - forget about perfect - but just learning by what I was taught and living by my own values. I might have stepped on a few ants - and a few other things as well - but I've never hurt anybody.
