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.

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.

So many people along the way,whatever it is you aspire to do, will tell you it can't be done. But it all it takes is imagination. You dream. You plan. You reach. There will be obstacles. There will doubters. There will be mistakes. But with hard work, with belief, with confidence and trust in yourself and those around you, there no limits.

You can't put a limit on anything. The more you dream, the farther you get.

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.

If I bring back only one gold people are going to say it's a disappointment. But not too many of them own an Olympic gold medal so if I get one I'm going to be happy.
