Pay back moving 泰国感人，有付出，才会有回报。值得致敬

3 minutes moving video, why do good people? Not because of morality, but because everyone is good, the society and everyone's operating costs will be reduced to the lowest, the biggest gains - I think the so-called morality is also based on this. So we're going to be good people. But sometimes difficult to do good, do good to catch it. I also confused, and then summed up the "only good people in the middle, there are good people", but this does not mean that we are going to be a bad person. We should have the heart of a good man - not to hurt others' interests, or to do evil. But you should have the means to protect yourself, not because you are a good person, you should sacrifice yourself for others, even when you are stressed by the name of the good people, but also to sacrifice others to do their own behavior - not you want to do evil, but to protect themselves.

3分钟感人视频，为什么要做好人？不是因为道德，而是因为大家都是好人了，这个社会和每个人的运行成本就会降到最低，收益达到最大——我认为所谓道德也是基于此产生的。所以我们要做个好人。但有时好人难做，做了好人还要挨骂。我也迷茫过，后来总结了一下“只有好人中间才有好人”，但这也不代表我们就要做个坏人。我们应该有个好人的心——不主动伤害别人的利益，不作恶。但更应该有保护自己的手段，不是因为你是好人就该牺牲自己成全别人，甚至当你被好人之名胁迫时，也要做出牺牲别人成全自己的举动——不是你要作恶，而是为了保护自己。
