What are some phenomena in your life that you still don't understand?

There are too many puzzling things in life. The smartest girl in the circle of friends married a stupid husband with no education. Handsome guy married a mediocre wife and still held it in his hand. When I was a child, the beautiful school flower lived a lonely and poor life. The worst performer became the president of a listed company. A scholarly family gives birth to hooligans, and a rogue family gives birth to heroes. People who have worked hard all their lives are not famous, but those who eat, drink and muddle along have risen to the top. People who pay attention to maintaining a healthy life have long died of cancer; People who eat, drink, gamble and smoke are as good as those who live to be 99. In the face of these irrational things, some people attribute it to fate, some people complain about injustice and cynicism, and others often sum up various "life lessons." In fact, all three people are wrong. These three kinds of people are one kind of people. All of us are such people, including myself. We all make these mistakes. These three mistakes can be simply summarized as: believing in fate, complaining about fate, and "calculating" fate. Fortune telling here refers to "trying to explain unreasonable things" in a broad sense. For example, the stupid husband married by a smart girl must have other advantages. For example, the beauty queen is miserable, and it must be a special "work" with bad personality. For example, the rebellious son of a scholarly family must be because his mother was busy with her career and didn't give him attention and love. We tell ourselves this kind of story every day. The brain is filled with the reasons for those "wonderful" events. Various forums are also full of analysis posts, gossip posts and educational posts. I've read a lot of this stuff myself. It's a shame to think about it ...
