Napoleon Hill interviewed and studied the 500 greatest wealth-makers of his time. From their examples, he uncovered the universal laws of success--principles that will work for anyone willing to put them into practice. The result, first published in 1938, was Think and Grow Rich. Napoleon Hill pointed the way out of the Great Depression and towards a prosperous future.

Seventy years later, we face new economic challenges, but the laws of success haven't changed. Think and Grow Rich is still the surest map to wealth.
Think And Grow Rich 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 first published.

Think and Grow Rich is listed in John C. Maxwell's A Lifetime "Must Read" Books List.
