If you have that spark that inspires other people, if you have a spark that gives resources to other people, that shares in really collaborative fashion, a spark of wit that kind of tells a story that gives people novel perspective of something, that's the kind of charisma that really leads to lasting power. It's not the kind of charisma that's seductive and self-aggrandizing. It's really a sort of a kind of social energy that really brings about the best in other people.
