There's such a high stigma around talking about your feelings or insecurities because, especially for men, we don't want to show that "weakness." But I'm always like, "OK, what would you rather do: Show weakness and get better, or continue to get worse and who knows where that leads?" There's something behind the suicide rate continuing to climb year after year. Why don't we ask for help?

I try to separate my personal life from swimming.

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.

Dream as big as you can dream, and anything is possible.

The one thing that's common to all successful people: They make a habit of doing things that unsuccessful people don't like to do.

I want to test my maximum and see how much I can do. And I want to change the world of swimming.

Eat, sleep and swim, that's all I can do.
