Water has always been a large part of my life, so for me now, being a father with another child on the way, I'm just teaching some of the small things I've been able to learn - and passing that onto the younger generation. Small things like turning your faucet off when you brush your teeth, not taking a 30-minute shower when you really don't need to. So I want to teach the younger generation to spread the message and make a difference. I'm almost more excited to do this than I was to swim.

If you want to be the best you have to do things that other people aren't willing to do.

It's not how you start, but it's how you finish.

Even in high school, I'd tell my mom I was sick of swimming and wanted to try to play golf. She wasn't too happy. She'd say, 'Think about this.' And I'd always end up getting back in the pool.

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.

If you're not on your 'A' game in our workouts every day, you're going to get absolutely smoked.

Things won’t go perfect. It’s all about how you adapt from those things and learn from mistakes.
