We need to know and understand happiness before we finally get it. A smart man must know to do something good even though it may be small, and not to do something wicked even though it may be tiny in the course of socializing. As long as we keep a kind heart and do everything morally and legally, we can live a placid life. But if we keep an evil heart and do whatever we want, we are indeed digging a tomb for ourselves. A smart man knows to learn a lesson from his falls for he knows that every setback is a precious experience leading to happiness in the future. He will not waste his time in critizing others. Instead, he tends to spend more time seeking his own happiness. He knows to keep a heart of conscience and not to spread others’ mistakes. He also knows to think before he leaps so that he will not feel regretful afterwards. Moreover, he knows to tolerate others, so he can naturally lead a happy life.
我们要认识幸福,了解幸福,才能够得到幸福的人生,聪明的人他必定懂得无论,处事,待人,接物都要做到,"勿以善小而不为,勿以恶小而为之'.人心正则人人从善,事事循理,自能安以相处,人心邪,则次情纵欲,任意妄行自必贻患无穷的道理.他知道跌倒的时候,不要白白地爬起来,任何一种磨练都是通向幸福的宝贵经验.他不会胡乱耗时间去批评别人,而是多花时间改善自己营造幸福.他懂得不会将自己的心田昧,更不会把他人的过失扬.他明白事不三思终会后悔,能够忍让自然幸福而无忧.

In order to possess a happy life, we need to know more about others, about the society, about our culture and history. We should be patriotic, abide by the law and realize our own responsibility, then we are doomed to have a happy life.
