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.

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.

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

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

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

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.
