Real Leaders: Abraham Lincoln and the Power of Emotional Discipline

In 1863, U.S. President Abraham Lincoln wrote a scathing letter to
his top Union general, who had squandered a chance to end the Civil
War. Then Lincoln folded it up and tucked it away in his desk. He
never sent it. Lincoln understood that the first action that comes
to mind is often counter-productive. In the third episode of a
four-part special series on leadership, HBR Editor in Chief Adi
Ignatius and Harvard Business School professor and historian Nancy
Koehn explore Lincoln’s career both before and during America’s
greatest crisis. They discover lessons on how to learn
continuously, communicate values, and exercise emotional
self-control.
