When you've learned to believe in yourself, there's no telling how good a player you can be. That's because you have the mental edge.

Do you believe you're a starter or a benchwarmer? Do you believe you're an all-star or an also- ran? If the answers to these questions are the latter, your play on the field will reflect it. But when you've learned to shut off outside influences and believe in yourself, there's no telling how good a player you can be.

There is a special sensation in getting good wood on the ball and driving a double down the left-field line as the crowd in the ballpark rises to its feet and cheers. But, I also remember how much fun I had as a skinny barefoot kid hitting a tennis ball with a broomstick on a quiet, dusty street in Panama.

Hitting is an art, but not an exact science.
