Either you run the day or the day runs you.
It's always too early to quit.
Wherever you are - be all there.
To be a good loser is to learn how to win.
Be gentle to all and stern with yourself.
Who seeks shall find.
You never know what motivates you.
Begin to be now what you will be hereafter.
I can, therefore I am.
If you've got a talent, protect it.
I think this is the biggest win in my career. To beat Venus in Wimbledon is just something amazing.
