When I was in Beijing, London, and also in Rio I was still a kid really, I didn't feel pressure. Now I'm a 26 year old woman. Being a lot older I feel those expectations. And it's definitely hard on my shoulders, to the extent where in training I'm ok but in competitions I panic, and I do stupid things. Working with [my psychologist], at these Games one of the things I'm proud of is I didn't have any panics. I was so happy about that - I went out and raced and enjoyed it.

The real problem is that the pain actually gets worse. You have created massive acidosis in your muscles so there is a huge quantity of hydrogen ions and the pH in your blood changes. For 15 minutes you lie there thinking, "God, this is really bad. I'm going to die. It has never been this bad before." And every time you think exactly the same thing. You have to lie to yourself by saying you're not doing a second set. Then, without moving for 15 minutes, almost to the second, I would roll over and think, "OK, I think I can do a second set now." During those sessions I have never felt more alive or so close to death.

Sometimes when I'm in the first round or second round, and I'm not playing well, I say, okay, just accept it. Don't get frustrated. Just accept and focus.

I was really vulnerable right before I left the coach, and I said to him, 'Are you still going to love me if I don't win this thing?'

Mr. Rogers lives on. There’s so many legions of people that grew up with him, and they’re still in a way growing up with him. He, of course, was a minister. ... And the children of the show, in the neighborhood, are his ministry. And what a beautiful thing that is. So I, to this day, when someone says, “What are you most proud to have accomplished?” I am so proud to have been a part of that.

My inability to keep track of personal possessions.

I love to break rules.

But part of practicing to me is actually an active enjoyment. When people ask, “How much do you practice and do you like practice?” Well, I think it’s always getting your mind to go from “I should” to “I want.” It’s like the magic button that only you can locate. When you’re doing the “should” thing, time happens very slowly. Ugh, I’ve been practicing forever! Fifteen minutes. But when you want to do something, an hour has passed. Your control of time depends on whether you should do something or whether you want to do something.

Perfection is always a desired goal, but it cannot be a primary goal. Expression has to be the primary goal, because otherwise, there is no need for an actual person to be there.

Very large bugs.
