You're Playing Or You're Not Playing. If

I Love Tennis, But I Just Don't Like Grass.

I'm Not A Materialistic Person.

I Can Improve It A Little Bit. But It's My Head, It's The Way I Am. So At The End Of The Day, I Will Be Who I Am And I Will Win How Much I Can Win.

It's Too Much Pressure. You Have To Think Match By Match And Moment By Moment Or It Drives You To Distraction. I'm Tired Of All The Talk About It. Everyone Is Obsessed With It...if I Was The Type Of Person Who Had Tennis, Tennis, Tennis All The Time And I Went To Bed And Ended Up Dreaming About Tennis, I Would Go Nuts.

I Think It's Difficult To Be No. 1. 'there's Too Much Attention, Too Much Expectation From Other People.
