Recently i had the opportunity to listen to Napoleon Hill’s Outwitting the Devil. Written in 1938, just before the second world war, it is an amazing transmission that makes it abundantly clear that Napoleon Hill had direct access to the collective unconscious.
If your understanding of Napoleon Hill begins and ends with Think and Grow Rich, then i would encourage you to take a look at the video below and get your hands on a copy of Outwitting the Devil.
Enjoy!
