Face: Have an animated face and make smiling a part of your regular repertoire. Make sure you flash your teeth.
Gestures: Be expressive but do not overdo it. Keep your fingers closed when you gesture, your hands below chin level and avoid arm or feet crossing.
Head Movement: Use Triple Nods when talking and Head Tilt when listening. Keep your chin up.
Eye Contact: Give the amount of eye contact that makes everyone feel comfortable. Unless looking at others is a cultural no-no, lookers gain more credibility than non-lookers. Posture: Lean forward when listening, stand straight when speaking.
Territory: Stand as close as you feel comfortable. If the other person moves back, don’t step forward again.
Mirror: Subtly mirror the body language of others.
