Who was Napoleon Hill?
"Napoleon Hill (October 26, 1883 – November 8, 1970) was an American author in the area of the new thought movement 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, is one of the best-selling books of all time. 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 to 1936." -Wikipedia
"Anything the mind of man can conceive and believe, it can be achieved," is one of Hill's hallmark expressions.
