There will be obstacles. There will be doubters. There will be mistakes. But with hard work... THERE ARE NO LIMITS.

One thing with me, and every goal I've had - in the sport of swimming, my mother didn't know my goals. The only person that knew my goals were my coaches.

I've been around water my whole life, so I basically really learned at a young age the importance of it but also one day, at one point, clean water will be hard to find. There's so many people throughout the world that don't have access to clean water. Obviously we're extremely fortunate to have the opportunities that we have and to have all the water that we have. Like I said, and I can't say it enough, we all should work together to try and conserve as much as we possible can.

Before, it came easy for me. I don't have two speeds anymore. I need to focus on the small things that I once took for granted.

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.

It's tough to put into words right now, but I finished my career how I wanted to. Through the ups and downs of my career I've still been able to do everything that I've ever wanted to accomplish.

When I race, I don't think about it; it just happens.
