All my life I'd woken up to tennis, tennis, tennis. Even if I don't go to practise, I'm thinking about it all day.

Depression isn't about, 'Woe is me, my life is this, that and the other', it's like having the worst flu all day that you just can't kick.

Venus told me the other day that champions don't get nervous in tight situations. That really helped me a lot. I decided I shouldn't get nervous and just do the best I can.

I think Courtney Owens, for never playing a tennis match a day in her life other than what she's played in practice, has done really well.

The day my son was born my life changed completely.

If you can keep playing tennis when somebody is shooting a gun down the street, that's concentration.
