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.
译文： 加入到微笑者和赞美者的行列来
当你对别人，别人也会对你报以，你自然会感觉很棒。即使他没有对你报以微笑，你也会感觉很棒，因为你认识到世界上最贫穷的人就是从不微笑的人，当你对那个人微笑，你立刻变得更加富有。
赞美也是这个道理。当你真诚地赞扬抑或恭维一个人时，他将立刻受益，更喜欢自己。当你让别人感觉更好时，你自己也会感觉更好。
