There is no rehearsal in life, and every day is live broadcast. This sentence is the life feeling of Professor Yi Zhongtian. This sentence is a very wonderful and appropriate metaphor, which profoundly reveals the philosophy of life. Rehearsal is a literary term that refers to the formal rehearsal before the performance. Live broadcast is a news term. Live broadcast is difficult, and there are no loopholes. Professor Yi used the metaphor of not rehearsing and being broadcast live every day to warn people to pay attention to life and not to the dance academy. Tao Yuanming's poem in Jin Dynasty said: If you don't return in your prime, it's rare to have a morning. It's time for people to encourage themselves when they reach middle age. Time goes by and waits for no one. Yue Fei's "Man Jiang Hong" also has words similar to "Don't be idle, turn your head to white and feel sad". There is an ancient saying that "young people will be sad if they don't work hard." In other words, life is short, so we should cherish it, grasp life, grasp the theme and stay away from triviality. Carry forward the spirit of doing now. Don't wait for emotions, you know, what comes out of the state is by no means waiting. The attitude of thinking determines the height of life. The difference between winners and losers is that winners always dominate and control their lives with the most positive thinking, the most optimistic spirit and the most brilliant experience. The god of fate is fair, while the goddess of success is picky. She only lets people close to her who can turn 24 hours a day into 48 hours. We should be good at managing time, be the master of time, and not be the slave of time. Some people say that the two most precious assets in life are mind and time. Time will run through a person's life. The way we treat time can determine our destiny. People with resources may not be successful, but those who make good use of resources will be successful. Strive for survival during the day and development at night. Go beyond ourselves every day and make our live broadcast more exciting!
