“You are entitled to know that two entities occupy your body. One of these entities is motivated by and responds to the impulse of fear. The other is motivated by and responds to the impulse of faith. Will you be guided by faith or will you allow fear to overtake you?”

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.
