Time is life, wasting other people's time for no reason is actually tantamount to killing people for money-Mr. Lu Xun, there are two things in the world that are most beautiful, one is lost and the other is not yet obtained. What you lost may be lost forever, but what you haven't got can still be won through hard work, so don't dwell on past memories, work hard, and all the good things belong to you! Once, the teacher told a thought-provoking story: it was late at night, and a businessman was walking on a dark mountain road. Suddenly, a mysterious voice came: "bend down and pick up more pebbles, which will be useful tomorrow!" " "The businessman bent down and picked up a few pebbles. The next day, when the businessman took a pebble out of his pocket and looked at it, he found that the so-called pebble turned out to be a shining gem! Naturally, it was these gems that made him regret it immediately-oh, my God! Why didn't you pick up more last night? After the story was finished, the teacher went on to say, "Students, this is actually a story told by scientist Pavlov to his students. Particularly thought-provoking, Pavlov said this meaningfully after the speech:' This is the meaning of education-when we grow up, we will find that the scientific knowledge we learned before is a precious gem; At this time, we will feel pity, because we have learned too little after all! "At this moment, I said meaningfully," Students, right? Education is obviously a precious' gem' for young people, but there are always people who are lazy because they are so tired that they miss many opportunities in vain. " We couldn't help nodding. Time is always running, trying to make every day have the best harvest. To realize the value of one year, you can ask a student who has failed in reconstruction. To realize the value of January, you can ask a premature mother. To realize the value of one week, you can ask the editor of an ordinary weekly. To realize the value of one hour, you can ask two lovers who are waiting to get together. To realize the value of one minute, you can ask a traveler who missed the train. To realize the value of one second, you can ask a lucky man who had a narrow escape. To realize the value of one millisecond, you can ask an athlete who missed a gold medal. Please cherish the good times you have, especially the good times you can share with some people who are worth paying. Don't forget that time waits for no one. Yesterday is history, tomorrow is unknown, and today is a gift. You don't know how to cherish it, but you don't know its value until you lose it. Rainstorm rainbow, sonorous rose! Have a favorite sky, cherish the present and imagine a bright future! No one can tell me what kind of history is wonderful, but I know what kind of history is true! When you have your own sky, do you know how to cherish it Do you have your own yesterday, today and tomorrow? ! ! You can think about it yourself
