     When do people decide whether or not they want to become friends? During their first four minutes

together, according to a book by Dr. Leonard Zunin. "Every time you meet someone in a social situation,

give him your undivided attention for four minutes. A lot of people's whole lives would change if they did

just that."

     When we are introduced to new people, we should try to appear friendly and self-confident. In

general, he says, "People like people who like themselves." On the other hand, we should not make the

other person think we are too sure of ourselves.

     Hearing such advice, one might say, "But I'm not a friendly, self-confident person. That's not my

nature. It would be dishonest for me to act that way." In reply, Dr. Zunin would claim that a little practice

can help us feel comfortable about changing our social habits. We can become accustomed to any

changes we choose to make in our personality. "It's like getting used to a new car. It may be unfamiliar at

first, but it goes much better than the old one."

     But isn't it dishonest to give the appearance of friendly self-confidence when we don't actually feel that way? Perhaps, but according to Dr. Zunin, "total honesty" is not always good for social relationships,

especially during the first few minutes of contact. There is a time for everything, and a certain amount of

play-acting may be best for the first few minutes of contact with a stranger. That is not the time to

complain about one's health or to mention faults one finds in other people. It is not the time to tell the

whole truth about one's opinions and impressions.

     The author also declares that interpersonal relations should be taught as a required course in every

school, along with reading, writing, and mathematics. In his opinion, success in life depends mainly on

how we get along with other people. That is at least as important as how much we know.
