1] Think And Grow Rich

Think and Grow Rich has been called the "Granddaddy of All Motivational Literature." The question, "What constitutes a winner?" was brazenly posed in it for the first time. Napoleon Hill, who posed the question and waited for the response, is today regarded as one of the greatest victors in history.
The most well-known teacher of success, who put in "a fortune and the best part of a lifetime of labour" to create the "Law of Success" theory that serves as the foundation of his books and is so well summed up in this one, spent a lot of time and money developing it.
Hill uses the success stories of millionaires from his period, including Andrew Carnegie, Thomas Edison, Henry Ford, and others, to demonstrate his concepts in the original 1937 edition of Think and Grow Rich. Arthur R. Pell, Ph.D., a well-known author, lecturer, and consultant in human resources management who is an authority on using Hill's ideas, skillfully weaves anecdotes about how modern millionaires and billionaires, like Bill Gates, Mary Kay Ash, Dave Thomas, and Sir John Templeton, came to be wealthy into the updated version. To avoid any barriers for a new readership, outdated or obscure language and examples are faithfully updated.
