My father was a foreman of a sugar-cane plantation in Rio Piedras, Puerto Rico. My first job was to drive the oxen that ploughed the cane fields. I would walk behind an ox, guiding him with a broomstick. For $ 1 a day, I worked eight hours straight, with no food breaks. It was very _ work, but it prepared me for life and taught me many lasting lessons. Because the plantation owners were always watching us, I had to be on time every day and work as hard as I could. I've never been late for any job since. I also learned about being respectful and faithful to the people you work for. More important, I earned my pay; it never entered my mind to say I was sick just because I didn't want to work. I was only six years old, but I was doing a man's job. Our family needed every dollar we could make because my father never earned more than $ 18 a week. Our home was a three-room wood shack with a dirty floor and no toilet. Nothing made me prouder than bringing home money to help my mother, father, two brothers and three sisters. This gave me self-esteem , one of the most important 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 the fairway and spot the balls as they landed, so the golfers could find them.
