A punch line. Don t rush. Keep eye contact and body language strong. Variety is the goal. Naturalness is the key.
Sincerity is essential.
What we SEE Facial expression should be pleasant. Not in our direction, or over our heads, but make eye contact with different people in all parts of the audience. Avoid looking at your notes. Only when you absolutely can t remember what you want to say next, look down, check notes, look up, then continue talking to us. Focus on audience not your visual aids.
