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.

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.

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.

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.

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

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.

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