You know the old-school leader archetype–a powerful presence walks into a room, and everyone stops in their tracks. While command-and-control leadership is a thing of the past, charisma is a timeless attribute.
You can harness your charisma to demonstrate your dominance over a room, to create a feeling of friendship and loyalty, or to communicate good or bad news. Your emotion at the time affects your posture and reveals your intentions subconsciously, so others will see and feel whatever signal you are giving off. Remember, back when you worked for someone else, how you could tell what kind of news the boss had before he opened his mouth at a meeting?
