My father says that if I hit 2,500 balls each day, I’ll hit 17,500 balls each week, and at the end of one year I’ll have hit nearly one million balls… - Andre Agassi

The finish line at the end of a career is no different from the finish line at the end of a
match. The objective is to get within reach of that finish line, because then it gives off a magnetic force. When you’re close, you can feel that force pulling you, and you can use that force to get across. But just before you come within range, or just after, you feel another force, equally strong, pushing you away. It’s inexplicable, mystical, these twin forces, these contradictory energies, but they both exist. I know, because I’ve spent much of my life seeking the one, fighting the other, and sometimes I’ve been stuck, suspended, bounced like a tennis ball between the two.

Life will throw everything but the kitchen sink in your path, and then it will throw the kitchen sink. It's your job to avoid the obstacles. If you let them stop you or distract you, you're not doing your job, and failing to do your job will cause regrets that paralyze you more than a bad back.

You don’t have to be the best in the world every time you go out there. You just have to be better than one guy.
