I don't have a strict diet. It's all about cramming in as many calories into my system as I possibly can. To be honest with you, I have a tough time keeping weight on.

I like to just think of myself as a normal person who just has a passion, has a goal and a dream and goes out and does it. And that's really how I've always lived my life.

My little son is already like me - my mom has always said I used to bounce off the wall and never stop talking or sit still. I'm starting to see that with him. I guess it's living proof he's part of me.

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 engaged in behavior which was regrettable and demonstrated bad judgment. I'm 23 years old and despite the successes I've had in the pool, I acted in a youthful and inappropriate way, not in a manner people have come to expect from me. For this, I am sorry. I promise my fans and the public it will not happen again.

Our time on Earth is already short enough. For me, it's like every single day I try to be as happy as I can. It's crazy to think about. We never have enough time. That's always the thing. We always want to do more. So it's about being able to spend time on the things that are most important to you. Life is a lot easier that way, and obviously life is pretty difficult a lot of the time.

I wanted to do something nobody ever did. This goes hand in hand with my goal of changing swimming.
