Big dreams are so damn tiring.

No athletes talk to themselves like tennis players. Pitchers, golfers, goalkeepers, they mutter to themselves, but tennis players talk to themselves-and answer. Tennis players look like lunatics in a public square.

You have to understand who you are and figure out a way to communicate it. It might be in a different industry, but it's about what pumps the blood through your veins, what makes you excited, what pushes your buttons. And then discovering the best way to communicate that, no matter how big or small; it's what you stand for, what you believe in, and what reflects who you are.

All the good stuff is on the other side of tired.

If you're ranked number one in the world it's because you've earned it, and I think the only way to really get there is to have that ability and to have it nurtured in a very competitive environment at an early age.

What makes something special is not just what you have to gain, but what you feel there is to lose.

I play tennis for a living even though I hate tennis, hate it with a dark and secret passion and always have.
