If You're A Champion, You Have To

In Tennis, At The End Of The Day You're A Winner Or A Loser. You Know Exactly Where You Stand... I Don't Need That Anymore. I Don't Need My Happiness, My Well-being, To Be Based On Winning And Losing.

Single-mindedness. I Hate To Say It Because I Don't Think It's The Best Thing For Developing A Person, But The Single-mindedness - Just Concentrating In The One Area - That's What It Takes To Be A Champion.

Ninety Percent Of My Game Is Mental. It's My Concentration That Has Gotten Me This Far. I Won't Even Call A Friend On The Day Of A Match. I'm Scared Of Disrupting My Concentration. I Don't Allow Any Competition With Tennis.

I Still Have This Image: I Can't Be Controversial, I Can't Say Things.

You've Got To Take The Initiative And Play Your Game. In A Decisive Set, Confidence Is The Difference.
