Lol, Deb! You know me... I never go for the obvious answers. :-) Vision, passion, etc. are definitely all factors. But one can have vision and the passion to pursue it, but only sweep others along in their wake without ever having created passionate followers. There's a transference that needs to take place, like when Martin Luther King, Jr. spoke, so that even if the leader is gone, the vision and passion lives on. To me, that comes from community-building; showing that one values others, even if they don't agree.

But, yes, I'm interested in what others have to say as well.
