Napoleon Hill is considered to have influenced more people into success than any other person in history. Born in a one-room cabin, he began his career as a journalist. His big break came when he was asked to interview steel-magnate Andrew Carnegie, who was so impressed with the young reporter that he convinced Hill to research and organize the world's first philosophy of individual achievement. The project took 20 years to complete. Hill wrote several best-selling books on the subject. Napoleon Hill's "Think And Grow Rich" is one of Nightingale-Conant's best-selling programs of all time.
