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.

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.

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.

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.

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.

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