My personal definition of leadership has really evolved over the past 14 years, during my tenure as CEO. And I think a good starting point is to talk about some of the things that leadership is not. It is not an abstract concept, it is not strictly philosophical, and it is not something that is just reserved for top management. Leadership, to me, is alive, it's real, it's vibrant. And it's personal. In our organization, we view every individual, regardless of where they are in the company, as a leader.
