It's a tough world out there and all the guys are fighting hard and the competition is really tough.
Anything is possible as long as you have the passion.
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.
When you are very little tennis should be fun, it should be a game.
If you win, fine, if you don't, you try again next year.
But whatever happens, when you leave London you feel like a winner because it's a great venue and it's so nice to be there with all the guys.
