The mark of great sportsmen is not how good they are at their best, but how good they are their worst.

I think the key is for women not to set any limits.

You can't live in the past, there's nothing you can do about it.

Sure I know where the press room is - I just look for where they throw the dog meat.

I shouldn't say I'm looking forward to leading a normal life, because I don't know what normal is.

Tennis has given me soul.

Just go out there and do what you have to do.

Just by being out you're doing your part. It's like recycling. You're doing your part for the environment if you recycle; you're doing your part for the gay movement if you're out.

I hope, when I stop, people will think that somehow I mattered.

Whoever said, "It's not whether you win or lose that counts," probably lost.

The more people come out, the less it will be an issue.

The difference between involvement and commitment is like ham and eggs. The chicken is involved; the pig is committed.

It is easier to do a job right than to explain why you didn't.

I just try to concentrate on concentrating.

Disability is a matter of perception. If you can do just one thing well, you're needed by someone.

If I feel strongly, I say it. I know I can do more good by being vocal than by staying quiet. I'd have a whole lot more money if I lied, but I wouldn't enjoy spending it.

I've been in the twilight of my career longer than most people have had their career.

The moment of victory is much too short to live for that and nothing else.

Labels are for filing. Labels are for clothing. Labels are not for people.

The mark of great sportsmen is not how good they are at their best, but how good they are their worst.

People in the States used to think that if girls were good at sports their sexuality would be affected.

After I retired, I was in Aspen, and after two months of being at home, I started to go nuts. I needed to go somewhere because that was the longest I never travelled.

Gender is irrelevant. Certainly the tennis ball doesn't know what the gender was of the tennis coach.

Goodbye 2010. If you were a fish, I'd throw you back.

I am just sorry my own mother had to live under that regime for most of her life. I was lucky. I got out and, 14 years later, Czechoslovakia became a free country. So I feel anger, even fury, at this bloody system that ruined so many people's lives for no reason whatsoever.

I can teach many sports, but obviously, tennis is the one. When you do other sports, you see things from different perspectives: different footwork drills, body positions, angles and geometry. All that stuff is helpful, and so when I do other sports, I can see things, because once you know one sport, then the other sport becomes more clear.

I didn't realize until I was doing commentary what a gladiator-like competition tennis is - other than no one dies. The crowd is waiting for the players to come, and they walk through the tunnel, and they get on the court, and they get out their rackets, their weapons, and now they start.

I do get pissed off when I'm at some gay event, and there's a 25-year-old, and he has no idea who I am. And I say, 'You need to know more about your gay history, boy.' I think the younger generation takes it a little bit for granted.

I think men are more adventurous in that they're more likely to take chances. Women play it safe. But now, maybe more of the women that see how it's working for the guys think, 'I can do that, too'. Maybe they'll pick male players, not necessarily female players; it's just whatever that match is that works for that player.

I was political by coming out of the womb. I was gay, and I wanted to play tennis.

I'll do some running with the dogs, ride a bike; if I go to gym it's usually for cardio. I don't do weights as much; every once in while, I throw in some pushups and do leg exercises to strengthen my legs.

I'm 58 years old. I got married for the first time - it's about time, right? Growing up as a gay woman, you just don't ever think about that, and then I thought, about 10 years ago, 'You know, I think within 10 years gay marriage will be legal.' And here we are, 10 years later, making it legal.

I've a great family, two children to take care of. Then, of course, I do commentary for TV. I do speak about various women's issues around the world - like LGBT, motivational speeches. I have a lot on my plate right now. But eventually, yes, I would like to pass on the knowledge and something that I would like to do.

I've been active in animal rights and all kinds of environmental stuff and children's charities over the years.

I've given many lessons in many sports over the years to many different people.

If a man can coach a female, why can't a female coach a male? When I was looking for a coach, the gender of the coach never occurred to me. It was about who I thought was good and who I could get along with and listen to.

Life is about challenges and how we face up to them and the attitude we take into every day life so hopefully we'll be able to motivate people to do more with their life.

My life is very well managed. I have a lot on my plate, and at the same time, there were still holes, and what I do and where I am dovetails nicely with what Agnieszka needs. I don't think I could be a coach for a Madison Keys because she needs somebody more hands-on. But Agnieszka is almost a finished product.

My worst memory is of my first dance lesson as a 14-year old in Prague. My mother put me in this silver and pink lame dress. My hair was all curled, and it was the first time I wore a garter belt. I felt so out of place!

Players are saying, 'I don't have to have a coach who has only played a little bit. Instead, I can have somebody who won something'.

Russia is now very far from being a communist country, but when I walked around Moscow, I kept glimpsing these haunting images. There were statues of Lenin and some neon signs of the hammer and sickle. I remembered myself then as a little girl, living under that oppression.

Sport doesn't know barriers, really. You are judged on your performance... how far you can jump, how fast you can run, how well you can hit a tennis ball.

That's the media now. They get lazy. Rumors become fact. Some blogger says something, next thing you know, it's in 'USA Today.'

The Williams girls compete extremely hard on court because they hate losing - it's just that they haven't played an awful lot of tennis over the years.

The goal for the Laureus Sport For Good Foundation is to give kids an opportunity to be involved in sports and hopefully learn some lessons along the way. We want to put them in a safe environment, help them if they need it and maybe they will get a scholarship to a school because of the skills that they learn. Sport is just a starting point.

The tennis ball doesn't know how old I am. The ball doesn't know if I'm a man or a woman or if I come from a communist country or not. Sport has always broken down these barriers.

To those people doubting Serena Williams, writing her off - do not do that to a champion.

Variety is what I would recommend: As variety is the spice of life in food, so it is in exercise. Change it up. But most of all, don't overdo it.

We're criminalizing economic inability to stay out of the system. Women get penalized more than men for the same crime; blacks get penalized more than whites for the same crime. We need to bring out more into the light, because it's not fair... I applaud Colin Kaepernick for speaking out.
