If you look at me, basically my whole entire life I've been around water. So when you look at a stat like, "If you leave the faucet running for two minutes while you brush your teeth you waste four gallons of water," to me that's mind-blowing. There are so many people that don't even have access to clean water, and people leave their faucets running. For me it was something that fit with things that I believe in.

I grew up around the pool with my sisters. Both of my sisters swam. I was always there. So I thought, why not? My mom put us in the water for water safety, so we were comfortable in the water in case anything ever happened. I learned that way, and started liking it more and more.

[Phelps] firmly denies that he takes drugs, suggesting that the notorious photo of him smoking from a bong was a one-time lapse of judgment.

I've always been fortunate in that I've been able to put myself in my own zone and relax. It comes naturally. I'm lucky to be that way

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?

We're all a little tired.

I think sometimes I guess you see records, say you want to get there and use that as motivation. In a way, it's kind of cool if there is a possibility to rewrite history and be up there with the greats of Olympic history.
