You don't do anybody any favours by being less than you are.

I always feel sad, to be honest, to see people badly injured. That's important because if someone's life is being changed like that it's extraordinarily important for that person - and you can't forget whether it was ten years ago, twenty or today. So I feel the same each time - I feel sad but I also feel that I should do the best I can to make it the best I can for them. So that's how I cope - by working.

One of the things I say is I don't think any of us should be average. Everybody's got a gift. The chance of finding your gift and then sharing it. There's just no room in this world to be average, you need to be the best you can be.

Australia has got some of the best sports people in the world, but we've also got some of the best scientists and innovators too, and that needs to be celebrated more.

We're not able to do anything about the bomb, but we can do something about the results. We're able to heal the people - not all of them. Some people died. But we're able to heal people, so we're doing something positive. And that's a great motivator.

You see it in schools all over... the concept that 'I'll be somewhat less than my best in order to make those around me feel more comfortable' is alive and well... I'm very keen that they understand that if they make themselves a little less than they can be, it is a one-way street to mediocrity.

I think plans failing is a really interesting question. I've been on a long journey. I'm 54 now and that's seriously old. I hope I still have heaps of years to go. Every day there's new success and some failures. But believe you me you can always get better - but things don't always go how you'd expect all the time. What you have to do is pick yourself up and keep going. That's part of life.
