There is no art more difficult than life. I think this problem can be understood from two aspects: first, it is not easy to understand others. Tell a story: there is a strong lock hanging on the gate, and an iron bar can't be pried open with great effort. The key came and his thin body got into the lock hole. With a slight turn, the big lock opened with a bang. The iron bar asked strangely, "Why can't I open it with so much effort, but you open it easily?" The key said, "Because I know his heart best." This story tells us that everyone's heart is like a locked door, no matter how thick the iron bar is, it can't be pried open. Only by honing yourself into a delicate key and entering other people's hearts can we understand others. And there are so many people in this world, is it easy for one person to understand so many people? Who can be your teacher and solve this problem? No, I'm alone. So it's hard to understand others. Second, it is difficult to cultivate yourself. There is a self-righteous young man who can't find an ideal job after graduation. In pain and despair, he came to the seaside and wanted to end his life. At this moment, an old man happened to pass by. The old man asked him why he was desperate. He said that he was not recognized by others and society, and no one appreciated and valued him. The old man picked up a grain of sand from the beach under his feet and showed it to the young people. Then he threw it on the ground and said to the young man, "Please pick up the sand I just threw on the ground." "This is impossible!" The young man said.

The old man didn't say anything, then took a shiny pearl out of his pocket and threw it on the ground. Then he said to the young man, "Can you pick it up?" "Of course!" The young man said. This story illustrates a great truth in life, that is, to make others and society recognize you, you must first create yourself and make yourself a pearl. Therefore, my understanding is that life is an art of understanding others and cultivating oneself. The former is difficult, the latter is not easy. Sometimes you have to cross the river by feeling the stones, sometimes you have to take many detours, sometimes you have to advance despite difficulties, and sometimes you have to know how to give up ... and all this can only be done through a lifetime of experience.
