Think and Grow Rich

Think and Grow Rich is a 1937 personal development and self-help book by Napoleon Hill. The book was inspired by a suggestion from Scottish-American business magnate and philanthropist Andrew Carnegie. While its title implies that the book deals with how to attain monetary wealth, the author explains that the philosophy taught in the book can be used to help people succeed in all lines of work and to do or be almost anything they want.

The book was first published during the Great Depression. At the time of Hill's death in 1970, Think and Grow Rich had sold more than 20 million copies, and by 2011, over 70 million copies had been sold worldwide. It remains the biggest seller of Napoleon Hill's books. Business Week magazine's Best Seller List ranked it the sixth best-selling paperback business book 70 years after it was published. Think and Grow Rich is listed in John C. Maxwell's A Lifetime "Must Read" Books List.
