To be a professional tennis player you need to put in these sort of hours.

It's better to have done because then you know what the player is going through and you understand the pressure, but then on the other hand I know a lot of people that were good players but not good coaches, and vice versa.

You should just enjoy it, but as soon as you decide that it is going to be your career, no matter whether you want to be a doctor or an architect or anything else, you need to work 5 hours a day.

If you lived the doubles, as I did, which was very stressful, you are sitting down in a chair experiencing a match without being able to hold a racquet in your hands.

You can be a little lonely because it's an individual sport.

I think our strength is this strong relationship we have all together.

I had a coach that was not a great player, but he taught with kids and juniors so that by the time he was 50 he was great. He helped me make the top 5 in the world and yet he wasn't a great player himself.

I retired because I had a knee injury, my cartilage was wearing out, it was painful and I couldn't put in the four hours of practice each day that I needed to.

To be a professional tennis player you need to put in these sort of hours.

But I still serve pretty big and that's one of my biggest weapons, so if my shoulder holds up and I can count on it, I can win a few matches and then you never know how the other guys are going to react to the fatigue and the length of the matches.

Anything is possible as long as you have the passion.

When you are very little tennis should be fun, it should be a game.

There are some guys you have problems beating because of their style - I always had difficulties with guys like Michael Chang and Andre Agassi because their returns were so good and they played so well in defence.

Suddenly in the end when it's over, you feel a big weight on your shoulders. That's the role of the captain. Unfortunately, it's sometimes like that in sport.

If you win, fine, if you don't, you try again next year.

When we want to reach a dream for the second time, you want it to come true, when you try so hard, you are so close to achieving it, it makes things very difficult to live with afterwards.

I think each player and myself live things differently because I have no physical effort to make.

When you are a professional sportsman all the guys are great competitors in the top 50.

More than specific memories of achievements, for me I remember the feeling you get when you were just at your very best - when you felt like you were floating across the court and could put the ball wherever you wanted.

It's a tough world out there and all the guys are fighting hard and the competition is really tough.

If Davis Cup was a little bit less or once every two years, I would be more inclined to play. But the way it is now, it is too much tennis for me.

I would like to see it go back to the wood racquets. To see the touch put back in tennis.

It's true I always try to be as seductive as possible but I wouldn't be here if I couldn't play tennis.

Golfers are forever working on mechanics. My tennis swing hasn't changed in 10 years.

When I was 12, every little girl in Russia was trying to wear her hair like mine and playing tennis.

What these guys are doing is great for Argentinean tennis. This is motivating other people.

I love to promote our sport. I love grass-roots tennis. I love coaching. I love all parts of the sport. I love the business side.

In tennis, you can make a couple of mistakes and still win. Not in golf. I played three rounds in that Tahoe event, and I was drained. Mentally, not physically.

We are merely the stars tennis-balls, struck and bandied which way please them.

I used to be told if I talked about my sexuality in any way that we wouldn't have a tennis tour.

What I want out of tennis is not necessarily just winning.

I've been playing tennis, and just whatever sport is in front of me I will do.

Tennis and golf are best played, not watched.

Yeah, I think there are many other important things in life, not just tennis.

My father actually moved out from Chicago just so he could play tennis 365 days a year, so it was - it was a place we played every day. We played before school. We played after school. We woke up. We played tennis. We brushed our teeth in that order.

The tennis wasn't really very much on my mind, so it wasn't like I was thinking about it all the time.

No, like I said, my dad was never really part of the tennis. His involvement around what I did with the tennis and with my mom and my grandparents was really not a part of my life.

Safin, in his way, is very talented. It is a joy to watch them play; it is tennis of a very high quality.

To meet my goals, I couldn't let up when I was playing tennis.

Both of us played basketball, and I played tennis and my knees are done. Now if you ask us head-to-head who wins at golf, I'm asking for a couple of strokes.

It was very hard for me to practice and enjoy my tennis, and I didn't know the why, so I worked with psychologists to try and see what was happening. They pushed me really hard.

I used to travel in tennis shoes; I am just not allowed to anymore. I'm an old hippie from San Francisco.

There are a lot of pretty girls. I am a tennis player first of all, that is why I am here, and if wasn't producing results no one would notice me.

I grew up on the tennis court with lots of other kids. There were like 40 kids all afternoon and I was one of the youngest ones, so I always had to chase everybody to keep up.

Tennis has given me soul.

Now I do bowling, golf, and tennis. I want to be a good bowler.

Tennis is a psychological sport, you have to keep a clear head. That is why I stopped playing.

I'm not saying I'm something special. I might play a little better tennis than other people, but it is because I was given the chance, and not many people are.

I am a hero worshiper. I love the number one tennis player. I love the number one baseball player. I want to see those records broken.
