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.

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

I think with practice, you can being whatever you want to be, and with a goal you can go in any direction that you want to go in.

I know it won't be eight medals again. If you want to compare me to that, that's your decision, not mine. I'm going out there to try to accomplish the things that I have in my mind and in my heart.

I would visualize the best- and worst-case scenarios. Whether I get disqualified or my goggles fill up with water or I lose my goggles or I come in last, I'm ready for anything.

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.

Before, it came easy for me. I don't have two speeds anymore. I need to focus on the small things that I once took for granted.
