The Law of Success in Sixteen Lessons (1928)

Published initially in 1928 as a multi-volume correspondence course, The Law of Success in Sixteen Lessons was commissioned originally at the request of Andrew Carnegie. Hill based his finding upon interviews of over 100 American millionaires across nearly 20 years, including such self-made industrial giants as Henry Ford, J. P. Morgan, John D. Rockefeller and Thomas Edison. Hill took The Law of Success lecture series across the country in the United States over a period of more than seven years.
