Eye contact is vital on a first date. When the other person is speaking, make sure you are not checking out the waitress, watching other people in the restaurant, or fiddling with your phone. Nothing says, “I could not possibly care less about what you’re saying” than this kind of behavior.

Appear confident—but not overly so. No one wants to date someone who is full of himself. So make sure to temper your extremely wonderful posture with some more modest body language, like a genuine smile and great eye contact.

Know how to listen, and know how to show it. Along with looking at your date, angle your head to show that you’re listening.

Know that a single touch on the forearm is powerful. When you’re getting to know someone, it’s the little things that convince him that you’re truly interested. A brush of your leg against his, or your hand touching his when you pass the menu shows that you’re not opposed to actually being in physical contact. And if you go out of your way to touch him—as in that touch to the forearm—that message is even clearer.
