Give a firm handshake. In most cultures, a solid handshake carries a lot of weight. Your handshake should be warm, friendly and sincere. If it is too firm or too weak, you may convey a negative impression. If you’re seated when you’re introduced to someone, stand before you shake his or her hand — it shows respect for yourself and the person you’re meeting. Remember to keep it short and sweet; many people will become uneasy if a handshake lasts for more than a few seconds. Finally, be sure to smile and make eye contact as you shake hands.
