Farrah Gray; 10 years old Successful Businessman

Farrah Gray was a successful businessman before he reached his teens, and his success story is so bizarre that it's almost impossible to believe. When he was 10 Gray formed a club that raised $15,000 for financing a lemonade stand, by 12 he had started a venture capital firm that raised $1 million from investors to help teenagers start their own business. Before he was 16 he had started business ventures that include pre-paid phone cards, One Stop Mailboxes & More franchises and The Teenscope "Youth AM/FM" interactive talk show. He became executive producer of a comedy show on the Las Vegas Strip, and was the owner of a food company that had orders exceeding $1.5 million.

Gray has since become a best-selling author. In 2005 his book Reallionaire was an international bestseller, and was even endorsed by Bill Clinton. Gray has written many books since then, including co-authoring Chicken Soup for the African-American Soul. But aside from all his success, Gray started his own non-profit Farrah Gray Foundation, which gives grants and scholarships to inner-city and students with at-risk backgrounds. And he's done all this well before his thirtieth birthday.
