Think and Grow Ric‪h‬

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 during the Great
Depression.[1] It remains the biggest seller of Napoleon Hill's
books, selling a claimed 30 million copies over the next 70 years (although
Alice Payne Hackett's 70 Years of Best Sellers suggests the figure was
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.

At Andrew Carnegie's bidding, Hill studied the characteristics of these
achievers and developed 15 "laws" of success intended to be applied by anybody
to achieve success. Think and Grow Rich! condenses these laws further and
provides the reader with 13 principles in the form of a philosophy of personal
achievement.
