When you smile at someone and they smile back, you automatically feel better. Even if they don’t smile back, you will feel better because you know the most destitute person in the world is the one without a smile. You immediately become richer by giving that person yours.

    The same goes for the compliment. When you sincerely compliment a person or extend him a courtesy, he is going to receive a direct benefit and like himself better. It is impossible for you to make someone feel better and no feel better yourself.
　　　
    當你對別人，別人也會對你報以，你自然會感覺很棒。即使他沒有對你報以微笑，你也會感覺很棒，因為你認識到世界上最貧窮的人就是從不微笑的人，當你對那個人微笑，你立刻變得更加富有。

    贊美也是這個道理。當你真誠地贊揚抑或恭維一個人時，他將立刻受益，更喜歡自己。當你讓別人感覺更好時，你自己也會感覺更好。
