High Quality Content by WIKIPEDIA articles! Napoleon Hill (October 26, 1883 – November 8, 1970) was an American author who was one of the earliest producers of the modern genre of personal-success literature. He is widely considered to be one of the great writers on success. His most famous work, Think and Grow Rich (1937), is one of the best-selling books of all time (at the time of Hill`s death in 1970, Think and Grow Rich had sold 20 million copies). Hill`s works examined the power of personal beliefs, and the role they play in personal success. He became an advisor to President Franklin D. Roosevelt from 1933-36. "What the mind of man can conceive and believe, it can achieve" is one of Hill`s hallmark expressions. How achievement actually occurs, and a formula for it that puts success in reach of the average person, were the focal points of Hill`s books.
