《增广贤文·下集》
人生就是一个起起落落的过程，富有的人谁能说自己能富一辈子，贫穷的人谁又能肯定他会穷一辈子，十年之内有多少人已经成功，又有多少人失败。
穷莫失志，富莫癫狂。天欲令其灭亡，必先让其疯狂。梢长人胆大，梢短人心慌。
Life is a process of ups and downs. Who can say for sure that a wealthy person will stay rich for the rest of their life, and who can say for sure that a poor person will stay poor for the rest of their life? How many people have succeeded in the past ten years, and how many have failed?
