I knew I was not a failure in any way, and so did those close to me. It doesn't matter if you fall short; it is never a failure to go after your goals with everything you've got.

I'm pretty lazy. My wife always says, "you're the laziest, most successful Olympian I've ever seen." How does that make sense? Honestly, if I have downtime, I'm really, really good at not doing anything.

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

There are so many things that I still want to do. My foundation, growing my brand . . . the list is endless. I'm honestly busier now than I was when I was swimming. It's kind of weird, but I feel like more of an adult because I have to do stuff every day. Whether it's checking emails or making phone calls or doing this and that, it's fun for me. It's the start of a new chapter. At times, it is frustrating, but I know it's not going to be easy to accomplish the goals that I want.

I want to test my maximum and see how much I can do. And I want to change the world of swimming.

I don't have a strict diet. It's all about cramming in as many calories into my system as I possibly can. To be honest with you, I have a tough time keeping weight on.

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.
