How you greet people reveals a great deal about you--your confidence, your attitude, your polish. Learn to give a good handshake. Begin with your hand parallel to the floor with your thumb pointing to the ceiling, and go all the way into your partner's hand until the space between thumbs and index fingers touch. Wrap your thumb and fingers all the way around your partner's hand and squeeze assertively--not painfully--and shake 3-4 times. Always stand for a handshake in business.
