I engaged in behavior which was regrettable and demonstrated bad judgment. I'm 23 years old and despite the successes I've had in the pool, I acted in a youthful and inappropriate way, not in a manner people have come to expect from me. For this, I am sorry. I promise my fans and the public it will not happen again.

With social media, so many people have anxiety and depression because of it. Of course technology is somewhat good, but it can present so many issues; more and more we're seeing what that's causing, and it's even leading to deaths. I just got finished doing a documentary called Anx with children talking about anxiety and recognizing their emotions and understanding them better. We need to let kids know it's OK to not be OK. And we need to help them be comfortable talking about it.

Our time on Earth is already short enough. For me, it's like every single day I try to be as happy as I can. It's crazy to think about. We never have enough time. That's always the thing. We always want to do more. So it's about being able to spend time on the things that are most important to you. Life is a lot easier that way, and obviously life is pretty difficult a lot of the time.

I learned how fast you can go from being an international hero to being a reference in a joke on a late night talk show.

I don't want to be the next Mark Spitz; I want to be the first Michael Phelps
