It's easy to forget when you're an elite athlete that everyone else gets nervous as well. Even the best people in the world, at whatever they do, they're still nervous

Going into that race I was going for the world record, just quietly, but I wasn't feeling at my best all week so it was hard to determine what would happen. I could not believe it, I went into shock, I'm still in shock.

I don't think I'm unbeatable, nobody is

I'm really quite exhausted at the moment, but you never know, you are always surprised at what you can find sometimes, and maybe I will find something deep within to find the desire to swim fast

I used to beat myself up everyday if I did not win an event. I am quite open about those things now and that has been a big change.

I've achieved everything I ever wanted. I've done three Olympics, world championships, I've been around the world and made good friends. But I still have the inner drive to do more, to be not just good, but to be great.

I can't control what everyone else swims but if all goes well I know there are no limits.
