If you want to be the best, you have to do things that other people aren't willing to do.

I know it won't be eight medals again. If you want to compare me to that, that's your decision, not mine. I'm going out there to try to accomplish the things that I have in my mind and in my heart.

I want to be able to look back and say, 'I've done everything I can, and I was successful.' I don't want to look back and say I should have done this or that. I'd like to change things for the younger generation of swimmers coming along.

People say to me, 'You're so lucky. You get to see the world.' But I don't. I go to the hotel and to the pools and back again. That's it.

This is my 20th year in the sport. I've known swimming and that's it. I don't want to swim past age 30; if I continue after this Olympics, and come back in 2016, I'll be 31. I'm looking forward to being able to see the other side of the fence.

I think to be - for me to be an American is - you know, it's one of the greatest things in the world for - you know, for me just because I've been able to grow up with everything. The freedom. You know, in my eyes this is the greatest country in the world.
