[thwarted]

I think the saying "Those who are most qualified to lead are the least likely to want to do it" (I can't find who said this, but wikiquote has a good collection of stuff on "leadership") applies. I've seen some terrible leaders (bosses, managers, coaches) get frustrated because the the person who falls into the leadership is followed and the designated "leader" isn't. And then there are groups who don't have a natural leader and who are completely ineffective because the person who is the leader is only doing it to be a role that appears to be carry some power.
