I Have A Russian Heart.

It's Pretty Hard Being A Tennis Player And Mother Theresa At The Same Time And That's Just The Way It Is.

If I'm Nervous, It Means I Had To Work Hard To Get There, Whether It's Playing In A Tournament Or Speaking At An Event. So I Try To Stop And Be Proud Of Getting To Live In That Moment.

When I Need To Push Myself, I Think Of All Those Nicely Polished Trophies Waiting To Be Lifted Up By The Winner - And How That Winner Might Be Me.

There Are Days When I Go Out On The Court And I Feel Like I Can't Miss A Ball.

I Don't Follow Other Players Or The Tournaments They Play. I Have My Own Schedule And Do My Own Thing. I Never Really Think, 'oh, I Want To Be Or Play Like So-and-so.' I Just Like Being Myself.
