There are many times I don't feel like going to work out, but I know if I do, I'll feel better.

My goal is to be No. 1 and to win Grand Slams.

I am constantly trying to improve my playing and hope to get more and more mental strength. I think these are two of the success keys.

Everything in moderation. I keep a healthy body, a healthy look. It's important not to be obsessive about anything - fitness, training, eating - because then you end up focusing on only that. And you can't obsess about anything when you're on the road.

Living through war has helped make me pretty strong.

One of the downsides of the job is that I am travelling so much, and I don't have so much time to go out and socialise as people who have a more traditional job might do, so it's hard.

A lot of coaches are very intense, which is good once you are working, but you don't want that all the time.

My parents were very protective of me and my brother, so they never talked to us about the situation in our country.

Ever since I was a young girl, even in school, I was always a perfectionist, and I always wanted to do my homework as soon as I got home. Everything had to be done properly.

I lift weights. I'll do a lot of running, a lot of cardio and strengthening. I use my body weight, a TRX sometimes. A lot of it is endurance.

All we see is gym, tennis court, and bed.

I really love fish, so I'll mix between that and meat, but I have to have protein. I can't survive without it.

I have a lot of belief in myself.

You want a coach who is going to push you and be strong and be in your corner when it's tough, but sometimes you have coaches who think they are more important than the players. That's where the conflicts come.

Everyone wants to be happy - people find happiness in different ways. While you want to pursue your career 100 percent, I think it is very hard to give 100 percent in something else. It's important to find this balance, and priorities change throughout life.

When someone recognises you or wants an interview, you think, 'You know, maybe I've done something good. Maybe I have a good result.' So if you see it in that way, it becomes a lot easier, and you realise that, actually, you're there and you've succeeded because of the media, because if it wasn't for them, no one in the world would know us.

I feel flattered that people like the way I look, but it doesn't help you win points.

I think, for me, it's very important to have a good team and to feel comfortable in the environment.

It was different when I was young, aged 20, playing the French Open. I didn't have so much experience. I just played tennis because I loved the game.

I get massages almost daily. Sometimes I fall asleep during the massage, but it's very important to have deep-tissue massages because that type recovers muscles best.

I like to come to a tournament with a specific playlist that I can listen to before going on the court. I like five or 10 minutes just for myself.

I have always liked my hair when it's braided, because if I don't, it kind of runs in my eyes when I hit.

I like to have my privacy. I don't like people knowing what I do in my free time. I am also a very shy person, but I understand that people want to know more.

As a people, Serbians are very tall, and we have olive skin and dark hair, which can look very nice. You have to be very beautiful to stand out.

Before a match, I need to be alone. I need to reach concentration and focus on the game ahead of me.

I don't really eat fried food. It's definitely a no go for me.

You learn you have to accept the way things are, and the sooner you accept them, the sooner you become at peace with them, and then the things start to get better.

Pressure comes from myself, because I expect a lot, but I am trying not to put so much pressure on tournaments and to be less emotional during matches.

When you have tough times, and when you learn you can't be perfect in every situation, it's hard to accept, you know, because I still do expect that. But you just have to, because, you know, it's not about the situation. It's how you deal with it. You always have a choice.

When we were kids, I remember we'd use lemon in our hair and go into the sun, hoping it would make us blond. Obviously, I have very dark hair and olive skin, and when I was a kid, I wanted to be blond, of course. It never worked.

I always keep my makeup really simple.

I do not follow superstitions on court.

I have a lot of hair, and it's quite heavy: Sometimes I'll braid it for a match so it's all together.

It's always been my dream to compete.

I was watching tennis on TV, and between games, they were showing a commercial for a tennis school. I wrote down the number, gave it to my mom, and said, 'This is what I want to do.' She thought it was a joke, but I was very stubborn, and I kept bringing it up.

I won two ITF tournaments in Japan in two weeks. I had to qualify for both of them, which meant that I won 16 matches in 15 days.

I think it's better not to mix professional life and personal life - although it is hard.

In cities like Miami, my hair can get so frizzy, it looks crazy. I use TRESemm Extra Hold hairspray. I use a lot of it.

I made some choices that weren't right in the past. It cost me in terms of my confidence and everything.

Once you are on court, it doesn't matter the way you look. It doesn't help you win points.

If I make a change to a young kid to play any sport, not only tennis, instead of spending time in front of the TV or computer, that is good. I want to give them a good example: 'Hey, go out and play and see the world.'

Even when I get dressed up to go out, I never use too much makeup.

You'd be surprised at how many times I'd hit the ball, and the hair would go straight into my eyes. That's why, even when I play indoors, I wear a visor, because it stops that, and I'll apply a lot of gel and hairspray to keep it tight.

If you are happy in your private life, and - that will affect your tennis, and that will help you, actually.

Obviously, if some young girl wants my advice and wants me to be her mentor, I would be very happy to offer that. But I don't really see myself as a coach.

I try not to think about the person, just their tactics, their weaknesses and strengths. I play against the ball.

When competing a lot and traveling, I have problems with my lower back because I'm always on the plane or sitting. That's something that does bother me from time to time, but I try to stay on top of it.

It's not good to stretch when you're cold. Get your heart rate up, and once you finish, take time to stretch and let your body calm down.

The media and press can be relentless, especially with women. Personally, while I take pride in my appearance and enjoy the compliments, when I'm on court, it is all about my game.
