Why do people live? How should life be spent to be meaningful? Ai Qing, a great poet, said: "Even if we are a candle, we should be so. Every night the candle will cry the wick away;" Even if we are a couple, there must be a glimmer of light at the critical moment. The poet Cang Kejia said: "Some people are dead and he is still alive;" "Some people are alive and he is dead." Everyone's life is different. How can I spend my life? I often hear people complain, why my face is not beautiful, why the weather is so bad today, why I live in such a poor family, why God does this to me … why do you complain about this and that? Life is not all the best, life is not perfect, on the contrary, ups and downs, joys and sorrows are commonplace. As the saying goes: when you are troubled, you will lose your mind; Laughter makes you younger. Don't complain, everyone's life will not be smooth sailing, and it is precisely because of these twists and turns that we can practice a colorful life. If you can always look at the problem from another angle, you may easily find that your life is still wonderful. You can't change your face, why don't you think about indulging in smiling; You can't change the weather. Why don't you change your mood? As the saying goes, you can't see the rainbow until after the storm. The same is true of life, and it is often tempered to achieve a wonderful life. When a writer from China came to the United States, he was always happy and surprised to see an old lady selling flowers. He picked a flower and asked, "Why are you always so happy?" The old lady's answer froze the writer. "The crucifixion of Jesus is the darkest day in the world, but Easter is three days later. Just wait three days, and all the troubles will disappear? " The writer was moved by the old lady's answer. An old lady can see life so freely and thoroughly. Edison, a great inventor, tried 1000 times to find the best material for filament, but all failed. A neighbor laughed at him: "How come you 1000 experiments have failed?" Edison said, "Didn't I find more than 1000 materials that are not suitable for filament?" Edison can look at failure from another angle and firmly believe that he will get the most suitable materials. Because of this self-confidence, he can make unremitting efforts and finally succeed. People should love life, love life, have self-confidence and make unremitting efforts towards the established goals. As Ai Qing said: "Even if we are a candle, we should be so. Every night, the candle will cry the wick away;" Even if we are a couple, there must be a glimmer of light at the critical moment. " If we can do this, then our life will be meaningful and our life will shine with different light. "Finally, I want to remind everyone that when encountering setbacks, don't always complain about this and that, but learn to think from different angles so as not to be knocked down by the' wind and rain' of life. Comments: This exercise can stick to the center and demonstrate the central argument of "don't complain about life, but learn to think from different angles" through examples. This article can also echo before and after, using this structure to highlight the center.
