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.

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.

My father's saying, The harder you work, the luckier you get.

I used to be squeamish a long time ago and I guess, secretly squeamish, no... but I have a huge respect for the human body and what we do and so I think it's a massive privilage for people to let you operate on them. And I used to be very "OOOH GOSH! THIS IS BAD!" but to see people bleeding and suffering is bad and I will never get over that, but being able to do something about it, means that you're no longer squeamish.

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

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.

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.
