Think and Grow Rich
by Napoleon Hill
Think and Grow Rich! is a motivational book written by Napoleon Hill and inspired by a suggestion by Scottish-American billionaire Andrew Carnegie. It was published in 1937 at the end of the Great Depression. It was the biggest seller of Napoleon Hill's books, selling a claimed 20 million copies over the next 50 years (although Alice Payne Hackett's 70 Years of Best Sellers suggests the figure was considerably lower).
The text of Think and Grow Rich! is founded on Hill's earlier work, The Law of Success, the result of more than twenty years of research based on Hill's close association with a large number of individuals who achieved great wealth during their lifetimes.
Napoleon Hill (October 25, 1883–November 8, 1970) was an American author who was one of the earliest producers of the modern genre of personal success literature. 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. "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 for the average person, were the focus of Hill's books.
