Most of the idle are apt to worry. Sorrow to sorrow, life is still so a life, the world is still so a world. Friend: From my many letters, it seems that you are not at peace these days. Trouble is a kind of old age, is a kind of morbid, you are still a eighteen or eighteen years old youth, so depressed, I really worry for you. General people like to talk about the metaphysics, you say trouble, he will be from the "philosophical dictionary" in drag out "world-weariness" "pessimistic philosophy" such as Tang Zai emperor zai words to describe your illness. I don't know how you feel. It seems to me that I myself have tasted trouble before, and I only feel that there is no way to worry. Not only others know, but also myself. There is no such thing as philosophy and outlook on life. I have also learned some lessons from philosophers. When I was in peace of mind, I admired the corridor philosophers of ancient Greece and believed that one should turn to nature instead of hating, liking and coveting. I admire Tolstoy and believe that the beauty of life lies in forgiveness and love. I admired Browning and believed that beauty was only possible when ugliness was present, but not entirely true; However, when the external sensation comes, the heart surges, and even the greatest philosophy cannot resist it. This is due to lack of self-cultivation, but how many young people have self-cultivation to the point of "unmoved"? In the past, my elders used to say to me "should not". They said that a young man like me should be vigorous, should not grow old, should strive for learning, should not put his worries and pleasures in his mind. Thank you, please keep this "should" prescription, the future trouble people are more! Friends, we are but the slaves of nature, to conquer nature, had to obey nature. Against nature, trouble is filled, to get rid of boredom, also must give your natural impulse a chance to vent. Life is active, good development, good creation. To be active, to be able to develop, to be able to create, is to obey nature and to enjoy happiness; Do not move, do not develop, do not create, is to destroy vitality, can not help feeling vexed. This fact can be seen in buzzwords such as "comfortable" when we feel happy and "depressed" when we feel unhappy. These two words can be used as adjectives or verbs. When used as adjectives, they describe the state of being fast or unhappy; When used as verbs, we can say that they give a reason for being fast or not. You feel troubled because your life is depressed; If you want to be happy, you must make your life can be comfortable, can vent. In popular words, there is the word "idle sorrow". Idle people are mostly easy to worry, because the vitality is still and uncomfortable in leisure time. Young people are easier to worry about than old people, because young people are more energetic. Children's vitality is also strong, but do not know sorrow, because they play all the time, so their vitality is not depressed. The children occasionally did not like it, so they burst into tears, and then the anger disappeared. How can you cry when adults feel upset? Coptis bitter in the heart, so the more bitter. Goethe wanted to commit suicide when he was a teenager because of his love affair. Fortunately, his writing changed and he buried himself in writing The Sorrows of Young Werther for two weeks. When the book was finished, his anger was relieved and his suicidal thoughts were eliminated. You don't have to write a book when you're worried. You can read a few Lamentations, listen to a tragedy, and drink your sorrows. I used to wonder why the more sad the story is, the more pleasant it is to read, until recently I realized this truth. In a word, sorrow is born in depression, the method of relieving sorrow is leaking; Stagnation because of static, the method of relief in motion. From the perspective of modern psychology, all the Confucian words on the mind nature are very crude. Only Mencius' idea of "complete nature" has a very profound and broad meaning. All moral doctrines are superficial if they do not start from the basis of "full nature". If you understand the word "do" thoroughly, I think the purpose of life is here, the way of life is also here. Human nature is complex, but human beings are animals, basic nature is nothing more than moving. We can find infinite pleasure in the middle of follower. I can prove this truth with two small things: Once I lived at home, I always liked to clean my study by myself. Every see books messy, dust all over the ground, you personally go and sweep, suddenly the cloudy world into a window bright clean, leisurely sitting, swim and let loose, but have indescribable comfort; For example, you are happy to play tennis, when you play hard, you still remember the so-called trouble between heaven and earth? You probably remember the story of Tao Kan of the Jin Dynasty. He had always been dismissed from office and had nothing to do, so he moved bricks. One hundred bricks moved from the house to the house in the morning, and one hundred bricks moved from the house to the house in the evening. People asked why, he said: "I am committed to the central Plains, too you Yi, afraid of unbearable." He also said to others, "Yu the Great, the sage, cherishes the Yin. As for everyone, you should cherish the Yin." In fact, why should we move bricks, but his old gentleman is still very strong, borrow this thing more activities, so as not to be depressed and bored. Friends, the most bitter sorrow of leisure! Sorrow to sorrow, life is still so a life, the world is still so a world. If you see yourself as great, you for trouble, when there is "disdain" to look at; If you look small, you should have a "not worth it" for trouble. I advise you to play more tennis, play more piano, plant more flowers, and carry more bricks. If you don't like these things, you can talk and laugh, run and jump, is fine. Here I wish you: talk smile, run jump!
