Technique #1 The Flooding Smile Don't flash an immediate smile when you greet someone, as though anyone who walked into your line of sight would be the beneficiary.
Instead, look at the other persons face for a second. Pause. Soak in their persona. Then let a big, warm, responsive smile flood over your face and overflow into your eyes. It will engulf the recipient like a warm wave. The split-second delay convinces people your flooding smile is genuine and only for them.
