Once You've Been Number One, You Can

Whatever Your Goal In Life, Be Proud Of Every Day That You Are Able To Work In That Direction.

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.

Competitive Toughness Is An Acquired Skill And Not An Inherited Gift.

Once You've Been Number One, You Can Never Be Satisfied With Less.

You Pay A Price For Everything In Life.
