I feel most at home in the water. I disappear. That's where I belong.

If I want to achieve the goals I've set, I've got to be in tip-top shape.

Anything is possible as long as you want it, you work for it. Doesn't matter what anyone else thinks, the only person that can really put pressure on you is yourself

Every day, there's always something to be worried about; you turn on the news and see something different every day, and it's terrible. Hopefully, as Americans, and as the inhabitants of the world, we can come together. We need to change lives - whether that's conserving water, destigmatizing mental health treatment or something else. We can change lives.

Being compared to Ian Thorpe, that could be one of the greatest compliments you could ever get in swimming - being compared to him and Mark Spitz.

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.

We need to make seeing a therapist more accessible; we've got to crack down on this and allow people the opportunity to seek help. It's going to be a game-changer. I would love people to become more vulnerable and reach out and ask for help. I would never want somebody to go through the feelings I had, almost exactly three years ago, of not wanting to be alive. That's a scary thing, and to think of where I am today compared to that - that's way bigger than winning a gold medal.
