     Do this and you'll be welcome anywhere.

     Why read this book to find out how to win friends? Why not study the technique of the greatest winner

of friends the world has ever known? Who is he? You may meet him coming down the street. When you get

within ten feet of him, he will begin to wag its tail. If you stop and pat him, he'll jump out of his skin to show

you how much he likes you. And you know this show of love. There is no secret motives (动机): he doesn't

want to sell you any real estate(房产),and he doesn't want to be your husband or wife.

      Did you ever stop to think that a dog is the only animal that doesn't have to work for a living? A hen has

to lay eggs; a cow has to give milk; and a canary has to sing. But a dog makes a living by giving you nothing

but love.

     When I was five years old, my father bought a little yellow-haired young dog for fifty cents. He was the

light and joy of my childhood. Every afternoon around four thirty, he would sit in the front yard with his

beautiful eyes staring at the road, and as soon as he heard my voice or saw me through the bush, he was off

like a shot, racing breathlessly up the hill to greet me with leaps of joy and barks of cheer.

      Tippy was my good companion (同伴) for five years. Then one night-I shall never forget it -he was killed

within ten feet of my head, killed by lightning. Tippy's death was the terrible event of my childhood. You never

read a book on psychology (心理学), Tippy. You didn't need to.

     You know that one can make more friends in months by really interested in other people than one can in

two years by trying to get other people interested in him. Let me repeat that. You can make more friends in

two months by becoming interested in other people than you can in two years by trying to get other people

interested in you.
