后悔失败学 The Law of Regret in Failurology

人生的主旋律就是后悔，就是那种怎么选都会后悔的后悔。因为时间不可倒流，人生无法重来。不存在什么假如当时，更没有平行时空去给你验证一下，如果当时你怎么怎么样，最后的结果可能会不会就不是这样了。不同的人在同一个人生十字路口会选择不一样的方向。但并不是和你同时站在那个路口，但是却做了另外一个选择的人，他后来走出的人生剧本，就会是你假如也做了那个选择的剧本。我也曾无数次懊悔过以前的选择，也时常在想，如果当初我做了另外一个选择，会不会后来就没有那么多懊悔和遗憾了？转眼多年过去了，我已经越来越相信，这就是人生，怎么选，都会后悔。与其后悔，不如既往不恋，把握当下，迎接未来。

The central theme of life is regret, which is the kind of regret you must experience whichever you choose. Because time cannot turn time back, life cannot restart life. There is no what if at that time; there is no parallel time to give you a test; the final result may not be different for each choice you made. Different people will choose different directions at the same crossroads of life. But it is not true that the one who stood on the same corner as you were will have the same future as if you chose to go in that direction. I have regretted the previous choice many times and often wonder if I had made another choice, would there have been less regret? Years have passed, I have become more and more convinced that this is life, how to choose, will regret. Rather than regret, it is better not to love in the past, seize the present and welcome the future.

失败学三大理论 Three Fundamental Theorems of Failurology

失败的的哲学必然性 The Philosophical Necessity of Failure

失败是基础态，成功是激发态；事实上，失败不是一种状态，而是一片海洋。在失败之海中，成功只是一个又一个的孤岛；你可能能够通过努力站上一个小岛，但是接下来你面对的，又是一片大海；从一个岛跳到另一个岛的旅程是无止尽的，在这个情况下，你为什么不直接去拥抱大海呢？ Failure is the basic state, success is the excited state. In fact, failure is not a state, it is an ocean in which successes are just several islands. You may be able to get to an island, but the next thing you faced, it's the ocean. The journey from island to island is endless, in which case, why don't you just embrace the ocean?

人类社会的结构性失败 Structural Failures of Human Society

在人类社会的结构中，特别是现行的资本主义框架内，99.99999%的人都是韭菜。最新的数据显示，2019年一年，全世界最富裕的前500名富豪，他们的净资产增加了25%，约合6万亿美金。而占全球99.99999%的人的资产增加的相对值和绝对值可能都无法与之媲美。在资本主义道德下，这些中产阶级和劳动者们一方面要对资本家感恩戴德，感谢他们提供的工作机会；另外一方面，又要合理化资本家的收入，觉得这一切都是资本家们应得的。在这个前提下，中产阶级和劳动者们的工作时间却加长了（到了996还不够）。在这种框架下，99.99999%的人都只能是资本的韭菜，贡献时间、消费和劳动力。 In human society, especially capitalism,99.99999% of people are leeks(It's a self-deprecating term implying they are being played for suckers, just faceless vegetables harvested by big companies and the government). According to the latest data, the net worth of the world's 500 richest people increased by 25% in 2019. And 99.99999% of the world's population may not be able to match that in terms of relative and absolute value. Under capitalist morality, the middle class and workers are beholden to the capitalists for the jobs they provide. On the other hand, they rationalize the income of capitalists, thinking that they deserve it, and on this premise, the middle class and workers work longer hours (996 is not enough). Under this framework,99.99999% of the people are just leves of capital, contributing time consumption and labor.

失败与自私相辅相成：失败在基因上的必然性 Failure and Selfishness Go Hand in Hand: The Genetic Inevitability of Failure

在人类长期进化的过程中，人类养成了自私的天性。毕竟在远古时期，不自私的人早就饿死了。在自私的加成下，人无法真心体会他人的痛苦，人只能一方面虚假的追求公平而另一方面又对自己所占有的所谓“优势”沾沾自喜。这种虚假平等和真实不平等的矛盾，让人永远不可能真心设计出人人成功的制度。人只能一方面把失败的原因归咎于自己不努力，却对全世界粮食远超人类所需但还是有人饿死这件事视而不见；又另一方面甘愿沦为他人的韭菜只为了自己多赚一点钱。甚至有人诞生了“是自私推动人类进步”这样荒谬绝伦的想法来为自己的困境合理化。因为人类自私的基因，导致人类无法克服“韭菜之障“达到真正的全局最优（只能达到某些人的局部最优，但简单的数学就能告诉我们，局部最优的和也不是全剧最优），因此人类社会是必然失败的。根本不值得期待。 During the evolution, people who were not selfish died of hunger long ago. With the addition of selfishness, people could not truly feel the pain of others. They pursue ostensible fairness in one hand, and they are complacent about the so-called advantages they possessed in another hand. This contradiction between ostensible equality and real inequality makes it impossible to truly design a system in which everyone succeeds. Ironically, people can only blame failure on their own lack of effort, but turn a blind eye to the fact that there are still people starving to death in a world where there is far more food than people need. People are willing to become a leek just to make a little more money for themselves. Some people have even come up with a absurd idea that "selfishness drives human progress" to justify their plight. Because human beings are genetically selfish and cannot overcome the "leek barrier". Achieving true global optimality (Today's world could only reach the local optimality for some people, but simple mathematics can tell us that local optimality are not global optimality), and therefore human society is a failure that is not worth expecting at all...!
