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.

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

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

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.

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.

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.
