Am I borring?

Some time ago one of the most features of leader for me was charisma.
Then life was life eh;-) and I didn't pay so much attention to it, but together with my freaked ideas about the future I thought ok what if I'm MCP and guys will ask me for roll call and what- big suchar. I do not have any charisma according to my self assessment:]
But follow up was the question what charisma means and whether depending on the situation, aim of leader etc it can be checked in the different way.
Still if I were to make a roll call alone what would I do? Definitelly no idea, but probably fool of myself:]
