Leadership is deeply personal. As people change, the way they lead has to change, too.Few leaders have navigated as much change as Joe Biden. He was elected to the Senate at 29 and will end his time as President at 82. The number of things he has witnessed and been a part of over the course of  his career is remarkable. His journey has been shaped by unlikely friendships and profound personal loss.I had the honor to sit down with President Biden at the White House to reflect on how his experiences have influenced his approach to both life and leadership.I chose to stay clear of politics and instead focused on the lessons that are applicable to all Americans…and indeed all people.  I hope you find it insightful and inspiring.This...is A Bit of Optimism.
