How to become even more charismatic

In General:
Open body posture, hands away from face when talking, stand up straight, relax, hands apart with palms forwards or upwards

To an individual:
Let people know they matter and you enjoy being around them, develop a genuine smile, nod when they talk, briefly touch them on the upper arm, and maintain eye contact

To a group:
Be comfortable as leader, move around to appear enthusiastic, lean slightly forward and look at all parts of the group

Message:
Move beyond status quo and make a difference, be controversial, be new, be simple to understand, be counter-intuitive, be fresh

Speech:
Be clear, fluent, forceful and articulate, evoke imagery, use an upbeat tempo, occasionally slow for tension or emphasis
