Sometimes it takes work to find a great group of friends whom you feel super comfortable and confident with.

No one who has gotten second place at a Grand Slam is ever like, 'Yeah, now I feel fine about it.' Everyone wants the other trophy. But it inspires you to work harder and get yourself in that position again so that you can use what you've learned.

There's just so much girl-on-girl hate. It happens to start in high school, and then it builds and gets bigger and bigger, and it seems like for some reason there's this mentality that if another girl does well, she's taking my spot.

I will never be able to say 'Yeah, O.K., I'm good,' you know? I will always want more, and more, and more.

I think it's especially hard when you start at an academy, because everything is decided for you. And then when you go with U.S.T.A., there's only so many decisions you can make.

Being away from the game and just remembering why I love competing and all of that, I think it helped me tremendously.

Serena's always been one of the best, and she will forever be one of the best tennis players in women's tennis.

I think it's definitely hard for the people who just out of nowhere come in and they do really well and all of the sudden the spotlight is on them.

I don't really identify myself as white or African-American. I'm just me. I'm Madison.

I think one big thing for me that I need to work on is being able to separate my feelings and emotions from my matches.

It's not the end of the world if I lose. I try to keep it all in perspective.

I'm a big fan of grass. It definitely suits my game.

I think the biggest thing is knowing that those thoughts of panic are probably going to go into your brain, and just accepting it... So that's been the biggest thing. Not fighting it and trying to think I'm going to have the perfect mentality the entire time. That's not going to happen.

You can almost get overwhelmed if you start focusing on Serena being on the other side of the court.

When I have a nice rhythm going, and I have my toss in the right spot, when everything is kind of working how it's supposed to be, I think it's just really easy, you know, and I don't have to overthink on it.

As far as cities, one of my favorite stops every year is Rome I think it's super fun to play there, because the tournament is really cool and the fans are super engaged, but also you get to walk around going to dinner, and the history - it's truly one of the most amazing cities in the world. I love it.

I know it's a cheesy thing to say, but I just want everyone to be able to get along.

Accept others for their differences, what makes them different. That's what makes the world the world.

I definitely have been working a lot on the mental side of my game.

Let's just stop being bullies face to face, online, whatever.

I started full-time training when I was 10, signed professionally when I was 14, and won my first match at the same age.

I grew up by the Mississippi River, and I would swim in that as a kid.

I've had people ask me whether I'm concerned about wearing makeup into a match, for example. One year, an on-court commentator asked one of the girls to twirl after the match. Surely, he's not going to go up to a man to ask, 'Can you do a spin for us?'

It wasn't until people started asking me what my plans were for the future - if I would go to college or go pro - that it really hit me what I wanted to do. I decided I wanted to go pro and try to be in Wimbledon.
