I have had extreme ups and downs. The biggest thing I learned after I broke my wrist is to never give up. Nothing in life will ever come easy. It depends on how you deal with those obstacles and how you overcome those obstacles. If you can overcome them, you're a stronger person. If you make mistakes along the way, as long as you never make that same mistake again, you're a successful person.

This is my 20th year in the sport. I've known swimming and that's it. I don't want to swim past age 30; if I continue after this Olympics, and come back in 2016, I'll be 31. I'm looking forward to being able to see the other side of the fence.

Perseverance, determination, commitment, and courage-those things are real. The desire for redemption drives you.

When we got in the race, we knew what we had to do and knew what we wanted to do. Having three of four guys from the American record 800 free relay is a pretty solid relay, so we thought we could take a crack at the U.S. Open record tonight. We're all a little tired, but that's fifth-fastest American relay ever, so it's not a bad time. We ended tonight on a great note.

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.

My mom put me and my sisters in the water to feel comfortable, to have water safety.

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.
