Think and Grow Rich - Napoleon Hill
The most famous of all teachers of success spent "a fortune and the better part of a lifetime of effort" to produce the "Law of Success" philosophy that forms the basis of his books and that is so powerfully summarized in this one.
In the original Think and Grow Rich, published in 1937, Hill draws on stories of Andrew Carnegie, Thomas Edison, Henry Ford, and other millionaires of his generation to illustrate his principles.
