"No man is an island" is a well-known line from John Donne's Devotion, written more than three hundred years ago. Even now people still agree with him. Without other people, life became empty and sad.  56

For some of us, though making friends is not difficult, we may not want to make the first move. It is also difficult at times to keep the friends we already have.

There are many books about friendship, but Dale Carnegie's How to Win Friends and Influence(影响) People, written in 1936, is the most famous. 57  It was later put into 28 languages.

Here is the list of advice from his book:

 58

Always greet with a smile. Begin with "excuse me" or "would you please", when you want to ask somebody. Remember to say "thank you" and try to be as helpful as you can.

Go out of your way to be nice.

59  Making some soup for a sick neighbour may seem like a little thing to you, but it will make your neighbour feel a lot better.

Remember names.

They say that the sweetest music to a person's ears is the sound of his or her own name.

 60

Try to understand other people's ways and ideas and learn something from them.

Listen patiently.

When someone is talking to you, look at him or her, listen carefully and say something when necessary.

This "How to" book about getting along with other people became a best seller.

It's also important to keep close friends in our daily life.

So we all need to have friends.

Be open-minded.

Be friendly and polite.

Try to help your friends get out of trouble.

Find some time to do some things for other people..
