Last night I pretty much pulled an all-nighter studying marathon to get prepared for my final exam in a public speaking course. In the process, I found charisma defined by my text as:
"Charisma is a form of dynamism. A charismatic person possesses charm, talent, magnetism, and other qualities that make the person attractive and energetic.
Well isn't that just nifty. In my opinion it kind of runs around the definition without ever really describing it. I think the key words are actually "attractive" and "energetic", as those are the realized results of charisma.
This word really is hard to definitively define.
