Napoleon Hill is one of the original personal growth advocates. In 1908, Andrew Carnegie commissioned Hill to interview 500 successful people to create a formula that anyone could comprehend and achieve. From that research Napoleon Hill developed what he called the “Philosophy of Achievement”.
One of the cornerstones of this philosophy is having a positive mental attitude. Hill’s “Think and Grow Rich” has been a best-seller for over 70 years. In this video Napoleon Hill explains in detail the concept of a positive mental attitude.
