“Opinions are the cheapest commodities on earth. Everyone has a flock of opinions ready to be wished upon anyone who will accept them. If you are influenced by "opinions" when you reach DECISIONS, you will not succeed in any undertaking.”

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.
