If I didn't swim my best, I'd think about it at school, at dinner, with my friends. It would drive me crazy.

I learned how fast you can go from being an international hero to being a reference in a joke on a late night talk show.

I'm pretty lazy. My wife always says, "you're the laziest, most successful Olympian I've ever seen." How does that make sense? Honestly, if I have downtime, I'm really, really good at not doing anything.

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.

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 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.

With social media, so many people have anxiety and depression because of it. Of course technology is somewhat good, but it can present so many issues; more and more we're seeing what that's causing, and it's even leading to deaths. I just got finished doing a documentary called Anx with children talking about anxiety and recognizing their emotions and understanding them better. We need to let kids know it's OK to not be OK. And we need to help them be comfortable talking about it.
