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

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

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.

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.

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