I could go through my Twitter account right now and there would be 10 horrible messages.

When you're 13 or 14, sometimes you wake up in a bad place. You feel like everything's out of your control. You don't know what to do.

I would like to think I can win a trophy or two, but the main thing for me is to focus on consistency.

I can play the No. 1 player in the world in a pretty close match.

Both of my grandmothers have always been really good bakers, and I was always in the kitchen helping them. Obviously I can't eat a lot of the things that I make, but just baking it and giving it to someone makes me feel really good.

My youngest sister does not like tennis at all, and she'll be the first one to tell you that, which I find pretty funny.

Everyone else wants to hear 'I wanna be Top 5,' or 'I want to be winning a Grand Slam.' Those are all goals of mine, but I'm not going to put a time limit on them.

I think I'll always consider the Quad Cities home.

Since I came on the tour so young and I won my first match, I've had a lot of comments like 'You'll be a top player one day.' I got to the point where, as nice as it was to hear that, I almost stopped listening to it. I was almost putting added pressure on myself.

We do get to do what we love. I think that's really special, and I think sometimes we get really caught up in the winning and the losing and rankings. And at the end of the day, we get to play a sport that we love for our jobs.

My nerves tend to dissipate once the match starts. When I know I've practiced as much as I can and I do my best and leave it all out there, I feel OK no matter what happens.

I think my biggest thing is learning when to hit which serve when, not doing the exact same thing over and over. Because O.K., great, it's 120 miles per hour, but they're standing right there, and they just block it back.

My first U.S. Open main draw, it was a big stadium and I wasn't really used to it.

Love' is a big step. It's a big word. You have to work your way to it.

Being able to rely on the matches I've won - at first they surprised me - but I've slowly been able to build confidence.

I think when I start thinking about results, I stop playing the right way because I start getting too nervous.

I think when you're younger and you're watching people play on TV, you always say that you want to be at the French Open - you want to be playing Grand Slams. But then actually being there doing it, it kind of blows you away thinking, Wow, I actually used to think maybe I could do that one day, and now I'm actually doing it.

Being an American, we're very lucky that all of the attention is very rarely just on one person. Unless you're Serena - then it's on you all the time.

Sometimes I have lapses of attention, and I can lose some points very quickly - that's been a big thing for him.

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.
