Harvard Business School professor Nancy Koehn talks about the surprising election of businessman Donald Trump as U.S. president, and what leaders throughout history can tell us about bridging divides and leading in times of uncertainty. Those three people and many other leaders who have moved through a very divisive struggle for what they believed was a worthy end, all of those leaders and many business leaders as well that I have studied that have turned around their company or saved their business, all of these people had the emotional discipline and then the consistency of action to turn away from the past, to turn away from what went wrong or all the divisiveness that was to face forward and say, we’re going to go forward together.
