In his office in downtown Omaha, Nebraska, Warren Buffett displays only one certificate of his education. It isn’t for his bachelors degree from the University of Nebraska, or his master of science in economics from Columbia Business School. It is for completing the “Dale Carnegie Course in Effective Speaking, Leadership Training, and the Art of Winning Friends and Influencing people”, dated January 23 1952.
The instructors on the course “made you do all these crazy things to get out of ourselves”, Mr Buffett says in the new HBO documentary Becoming Warren Buffett
. But “if I hadn’t had done that, my whole life would have been different”.
