How To Be More Charismatic

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, new, simple to understand, counter-intuitive
Speech: Be clear, fluent, forceful and articulate, evoke imagery, use an upbeat tempo, occasionally slow for tension or emphasis
