Henry Ford's Mastermind Group In "Think and Grow Rich", Napoleon Hill talks about Henry Ford's Mastermind Group:
"Men take on the nature and the habits and the power of thought of those with whom they associate in a spirit of sympathy and harmony. Through his association with Edison, Burbank, Burroughs, and Firestone, Mr. Ford added to his own brain power the sum and substance of the intelligence, experience, knowledge, and spiritual forces of these four men. Moreover, he appropriated and made use of the Master Mind principle."
Who are we to doubt these business leaders.
