What do the most powerful people in the world do after they've achieved success? Jared Cohen is a history buff and a presidential historian. His latest book, “Life After Power,” is a fascinating exploration about what seven American presidents did after leaving the most influential job in the world. In this episode of ReThinking with Adam Grant, another podcast in the TED Audio Collective, Adam and Jared discuss the psychology of the founding fathers, debate the pros and cons of pursuing a legacy, and share what these historic figures can teach us all about pursuing and finding purpose.
