When the Commodore 64 personal computer debuted, I convinced myself that I had to have it even though its price was out of my mother’s range. So I decided to earn the money myself. I mowed every yard I could find that summer for a few dollars each, yet it still wasn’t enough. The grass just didn’t grow fast enough. So my dad agreed to help me raise the rest of the money by driving me to one of the watermelon farms south of town, loading up his truck with wholesale melons and driving me around to sell them.
