Think and Grow Rich

Napoleon Hill published this distillation of 20 years of interviews with over 500 wealthy Americans in 1937, and it has sold more than 100 million copies since. Its central thesis — that a burning desire, a definite plan, and sustained belief are the prerequisites of all achievement — became the philosophical foundation of the entire modern success literature movement. Despite ongoing controversies about Hill's methods, Think and Grow Rich is cited by more self-made millionaires as a formative text than almost any other book.
