I got my best financial advice when I was 16. I met this kid who was only eight, but he seemed smart, and he said, "If you give me $5, I'll invest it in a company I plan to start someday. In return I'll pay you 10% of the profits."
That young man was Bill Gates. I'm sure he'll remember this, now that it has been revealed in a reputable magazine.
