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

The second I was on the tennis court, I had the structure I wanted. I was in complete control of what I was doing.

Sometimes I have lapses of attention, and I can lose some points very quickly.

I'm not the best at hiding my emotions.

The expectation from other people kind of gets on me.

I was getting, at like 18, 'Why haven't you won a Grand Slam yet?'

I don't really focus on other people's expectations of me. I only care what my own expectations are.

I've been on my own and traveling for years now.

It can be tough and lonely on the road, but at the end of the day we get to play professional tennis for a living, and I wouldn't change it for the world.

For me it's just never being satisfied with what I've done and always just wanting more and more.

I really wanted a tennis dress. My parents told me that if I played, they would buy me one. I was like, 'Hey, I'll try it.'

Every single day, my parents fed me balls. Eventually it turned into having a coach, and then it went to being at an academy. You know, it worked out pretty well.

My priority when I get off the plane and get to a city is get situated at the hotel and then go on site and get a good practice in. Sometimes working out can help with getting over jet lag as well.

I've tried my best to be a good role model for my two younger sisters.

It was tough because I was on the road so much, on top of everything. I went through what every girl goes through emotionally in life, going through high school. It wasn't easy.

I think I have slowly kind of had my name out there a little bit more and had some success.

My mom has always been that person who keeps me grounded, and my two younger sisters are always cheering me on.

I would be lying if I said I wanted to wake up and work out every day.

My mom and grandma always told me: if you don't have anything nice to say, don't say anything at all. It's something everyone needs to be more conscious about. Putting more positive energy out into the world would be so beneficial.

Usually before matches I eat plain pasta with a little bit olive oil, salt, pepper and chicken.

We do a lot of lifting, and mix it up with upper body and lower body. A lot of circuit training for cardio. I hate just doing long distance running, so I do 5 or 6 different exercises for 20 to 30 seconds then move to the next one.

I think it's just really good to be honest with yourself and if I'm not feeling up for something I have no problem staying in my room in ordering some food and relaxing and managing my energy and kind of just checking in with myself throughout the day.

I'm obsessed with my couch. I have the greenest couch on the planet.

I love Dennis Quaid! I don't know why, but I've loved him forever.

I'm one of those people who writes out words. All of my text messages? You can read them. Everyone would know what I'm trying to say. My sister will say 'BTW.' Do you mean 'by the way'? Is that what you're trying to say?

Sometimes you have to give yourself a break.

People aren't winning Slams at 21 anymore. It's later.

I loved dance, but tennis felt more natural to me. Dance did help with my rhythm and balance.

I try to live in the moment and not overthink things because then you start putting yourself in situations that you don't want to be in pressure-wise.

A lot of people just assume men's tennis is better.

I make a little goal every day and work toward achieving it - even if it's the smallest little thing.

On those days when you don't want to get up, I think, I'm going to get through my entire practice without saying how tired I am or I try not to complain just because I was in a bad mood when I woke up. Even if it's not perfect and I slip up, I can catch myself and make myself of aware of where my mental space is at and move on.

I enjoy lifting weights more than I enjoy getting on the treadmill to run.

I've always loved Charleston. It's always been one of my favorite tournaments.

People always look shocked when I tell them the Cincinnati Open is one of my favorite tournaments.

You can get eight thousand great, amazing messages, and someone will send you one thing that you're maybe self-conscious about, and that's the only thing in your head for the rest of the day.

I have one of those bodies that is just a little more injury-prone.

I'm really lucky to have Lindsay Davenport as my coach. She was number one in the world, and she's won Grand Slams, so if there's any person who can help me get through, it's her. Getting her advice is very special for me.

I expect a lot for myself.

When people say that American tennis is dead and things like that, you kind of take it a little personal.

Poor is the man whose pleasures depend on the permission of another.

Be strong, believe in freedom and in God, love yourself, understand your sexuality, have a sense of humor, masturbate, don't judge people by their religion, color or sexual habits, love life and your family.

I am my own experiment. I am my own work of art.

I stand for freedom of expression, doing what you believe in, and going after your dreams.

One thing I've learned is that I'm not the owner of my talent; I'm the manager of it.

When I'm hungry, I eat. When I'm thirsty, I drink. When I feel like saying something, I say it.

I know I'm not the greatest singer or dancer, but that doesn't interest me. I'm interested in being provocative and pushing people's buttons.

I want to be like Gandhi, and Martin Luther King, and John Lennon... but I want to stay alive.

With all the chaos, pain and suffering in the world, the fact that my adoption of a child from who was living in an orphanage, you know, was the number one story for a week in the world. To me, that says more about our inability to focus on the real problems.

I'm tough, ambitious, and I know exactly what I want.
