Kokichi Tsuburaya, Sean, class 0/5 of Fast and Slow High School/KLOC-was once the best Japanese long-distance runner. The love of running since childhood made him practice the speed and rhythm like a locomotive. However, full of confidence, he was surpassed in the Japanese Olympic Games. Determined to get revenge, he started training again the next day, day after day, rain or shine, but in the end he failed to appear in Mexico. He committed suicide, leaving a suicide note: "I am tired and can't run." This is exactly the most difficult thing that people often think of. Yuan Gu also exchanged his life for this sentence! On the runway full of opponents, in the training full of counterattacks, under the pressure of fame and fortune, Yuangu, even anyone, will become difficult and eventually fall down. This is also the runway we are stepping into now. You chase after me and get rid of the fittest, which is the survival law given to us by today's fast-developing society. I admit that this society needs to be fast. From two-wheeled, three-wheeled to four-wheeled aircraft magnetic levitation; From fast food, instant noodles to instant coffee; From telegrams to telephone videos; Writing letters and keeping diaries have become Weibo, and communication is very short. Gradually, quick success has become a magnifying glass of greed and a catalyst for the growth of human greed. Clenbuterol is not enough, and plasticizer is famous; Henan "bodybuilding pig" was exposed, and "cosmetic pig" stood up again in Chongqing. Blindly seeking quick success and instant benefit makes producers forget the value of living. But I "understand" them, as Stalin said, "Slowing down means falling behind, and falling behind means being beaten." Living in such an era, we are not qualified to slow down. However, when I think about it, a person's life is nothing more than a short journey from cradle to grave. If they never sit still and walk slowly, they will get ahead of others and gain more fame and fortune. In the end, "coming and going naked" was too heavy to take away his soul, just dragging the dead, and the previous speed became particularly slow. This is exactly what the extremes meet. Then, why don't you slow down and watch people come and go, while I just sit there as cool as a cucumber. Yuan Gu was the last one to realize it, but after all, he was timid and went to the extreme of stopping quickly. I mean, it really took a lot of courage. Sinopec, a high-income company, began to lament the lack of money after the oil price dropped slightly. How can ordinary people not worry about their own small gains and losses? This kind of slowness needs the innermost contradiction and concession, the truest dream and the most sincere mentality, and the inner rhythm. This really has nothing to do with the ups and downs of the outside world. Even if it is a second when facing yourself, it is gratifying. Writing here, I want to end with a fable: a group of people hurried on, suddenly, a person stopped, and everyone asked, "Why don't you go?" The man smiled and said, "I walked so fast that my soul has fallen behind." I will wait. "
