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.

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.

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

I can do something about people who need me, who have been injured. So the biggest thing about being a doctor is my education and training means I can help people to reduce their suffering and that's what being a doctor is, to reduce suffering and to try to improve the life of people who have been injured.

Being able to influence the outcome, being able to do something about it, to be able to stop the bleeding. You're not being useful if you're just standing there going "Oh, that's awful!" You're only useful if you actually do something about it and I think that goes for everything. If you actually do something about what's in front of you, then you are actually contributing and you haven't got time to be self-centred or sorry for yourself. You should be doing something about the person you really should feel sorry for.

People can lose so much skin that it has a huge effect on the body and when they scar they are affected for life. I've worked in this area and have for years tried to improve spray on skin cells, but this is just one part of the jigsaw towards making it better. We needed to get it on quicker then we can reduce the scarring. That's my motivation, my drive towards making it better.

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.
