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 person's 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.
