Tennis is a huge part of my life, but I don't base my self-value or my self-worth or the quality of my life on my results on the court.
It's every Williams for themself.
When youre on top, youre on top.
I have to say accounting almost killed me.
Serena and I, we don't have anything to prove ... we still set a very high standard.
To stay interested in tennis, I have to mix it up with other things.
