What genius lies asleep in your brain? This is the question asked of us by Napoleon Hill. Originally published in 1937, and selling more than 60 million copies worldwide, Hill's Think and Grow Rich is the classic motivational book. Inspired by Andrew Carnegie, Hill studied the work and lives of some of the most successful people of the Industrial Era including Ford, Wrigley, Eastman, Rockefeller, Edison, Woolworth, Burbank, Morgan, and Firestone as well as three United States Presidents. From his 20 plus years of research into the characteristics of what launched these individuals into greatness and wealth, Hill developed his 13 universal principles, meant to inspire any individual to a richer, fuller life. The true genius of his writing is the simple way in which he explains that wealth comes from seeing your goal in your mind and making it happen, no matter what.
