My father was a foreman of a sugar-cane plantation in Rio Piedras, Puerto Rico. My first jobwas to drive the oxen that plowed the cane fields. I would walk behind an ox, guiding him with abroomstick. For $1 a day, I worked eight hours straight, with no food breaks.
It was very tediou work, but it prepared me for life and taught me many lasting lessons. Be-cause the plantation owners were always watching us, I had to be on time every day and work ashard as I could. I' ve never been late for any job since. I also learned about being respectful andloyal to the people you work for.. More important, I earned my pay.
I was only six years old, but I was doing a man' s job. Our family needed every dollar wecould make because my father never earned more than $18 a week. Our home was a three-roomwood shack with dirty floor and no toilet. Nothing made me prouder than bringing home money tohelp my mother, father, two brothers and three sisters. This gave me self-esteem, one of the mostimportant things a person can have.
When I was seven, I got work at a golf course near our house. My job was to stand down thefairway and spot the balls as they landed so the golfers could find them. Losing a ball meant youwere fired, so I never miss one. Some nights I would lie in bed and dream of making thousands ofdollars playing golf and being able to buy a bicycle.
The more I dreamed, the more I thought. Why not? I made my first golf club out of guavalimb and a piece of pipe. Then I hammered an empty tin can into the shape of a ball. And finallyI dug two small holes in the ground and hit the ball back and forth. I practiced with the same devo-tion and intensity I learned working in the field--except now I was driving golf balls with club, notoxen with a broomstick.
