Not every child is cut out for an individual sport.
I think team sports probably teach you more about giving - about being unselfish and being flexible.
Single-mindedness. I hate to say it because I don't think it's the best thing for developing a person, but the single-mindedness - just concentrating in the one area - that's what it takes to be a champion.
Find something that you're really interested in doing in your life. Pursue it, set goals, and commit yourself to excellence. Do the best you can.
If I win several tournaments in a row, I get so confident I'm in a cloud. A loss gets me eager again.
If you can react the same way to winning and losing, that's a big accomplishment. That quality is important because it stays with you the rest of your life, and there's going to be a life after tennis that's a lot longer than your tennis life.
You've got to take the initiative and play your game. In a decisive set, confidence is the difference.
