“Definiteness of decision always requires courage, sometimes very great courage. The fifty-six men who signed the Declaration of Independence staked their lives on the decision to affix their signatures to that document.”

American self-help author

Napoleon Hill was an American self-help author. He is best known for Think and Grow Rich, published in 1937, which became one of the best-selling self-help books of all time. His writing presented success as something that can be shaped by belief and sustained expectation. Most of his books set out principles for achieving success, and his work returned often to the idea that determined thought is central to improving one’s life.
