I Don't Worry About What My Opponent

I'm Always On The Go. I Love Doing Things Until I Hit Rock Bottom. Then I Need My 12 Hours Of Sleep, And I'm On The Go Again.

I Think That's Why I Play Tennis, Because Of The Challenge, Because Of The Competition, .. That's Why We Love To Play Tiebreaker In The Third Set. It Makes It More Exciting, And The Bigger Support In The Stand, And More Fans Involved In It. I Really Enjoyed The Competition And Took A Lot Of Hard Work To Make Myself No. 1 At 18 Years Old.

I Had So Many Outs In My Career. I Could Have Said, I Don’t Need This. I Have Money; I Have Fame; I Have Victories; I Have Grand Slams. But When Your Love For Something Is Bigger Than All Those Things, You Continue To Keep Getting Up In The Morning When It’s Freezing Outside, When You Know That It Can Be The Most Difficult Day, When Nothing Is Working, When You Feel Like The Belief Sometimes Isn’t There From The Outside World, And You Seem So Small. But You Can Achieve Great Things When You Don’t Listen To All Those Things.

I Think When You Have Surgery On Any Part Of Your Body, It's Never Going To Be The Same.

No Matter What You Study, The Thing That You Know Best Is What You Grew Up With.
