Think and Grow Rich is a motivational personal development and self-help book by Napoleon Hill. This is a re-print of the original version from 1937. The book was inspired by a suggestion from Scottish-American businessman Andrew Carnegie. While the title implies that this book deals with how to get rich, 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. A classic book and a 'must read' for every entrepreneur and business person.
