How to understand "industry is good at diligence, but barren at play"? What are the real examples to illustrate?

Han Yu said in "A Solution to Advanced Studies": "Industry is good at diligence, but it is scarce at play; What is done is thought, but it is destroyed. " It means that the improvement of study lies in diligence and hard work, and the neglect of study lies in play and amusement; The success of being a man lies in deliberation, but the failure lies in persistence. It has been 26 years since I first came into contact with English letters. However, I really fell in love with English when I was 2 years old. That year, my father, a professor at Nanjing University, went to Brown University in Providence, USA for work and research reasons. My father is very busy at work in America, but he calls me almost every day. He has repeatedly told me to learn English well, and he will definitely let me immigrate to America. English will be very important. At that time, I was a sophomore in the Chinese Department of Nanjing University. I was reading hundred schools of thought's classic works and China's great works of modern literature in a planned way every day. I was dreaming of becoming a master of Chinese studies. I really worked hard in this direction every day. I spent all my time reading and studying China's language and literature. In the Chinese Department, everyone despises English learning. At that time, I always scored only 6 points in English, but I was obsessed and crazy about China's Chinese studies. My father's letters and long-distance overseas phone calls made me understand that there is another world outside China that we need to explore and know. I began to find that there are many people in the world who are doing cultural exchanges between countries like my father, deepening the understanding between nations and eliminating barriers. I vaguely realized at that time that English was so important that it would be great if China's information and works could be transmitted to the world through my mouth and hands. Everything comes to him who waits, my English grades are slowly rising, I begin to feel the interest in English learning, and I begin to enjoy the fun English brings me. Gradually, I can read some English short articles, and these English words seem to come alive before my eyes. I took the TOEFL test soon and got more than 55 points, which is really a great encouragement for a person who has not studied English for a long time. I really need such encouragement. My English study time is increasing every day. I keep memorizing English words and listening to English broadcasts. My understanding of English is deepening. I constantly test my English study through reading and testing, thus enhancing my confidence in English study. Inadvertently, I realized that I was fascinated by English, and English learning became an indispensable part of my life. I even felt that English had become my lover who knew each other and loved each other. My life without English was unimaginable, even for a minute. I hope that when I leave this world, as long as I am accompanied by English, she will never abandon me, never abandon me, give me fun, and eliminate the loneliness and boredom of my life. She makes me cry for her again and again. I can't imagine life without English, and I am crazy about English. In this life, I will never be separated from English, and we will be together in the afterlife. My goal in life has changed in this way. A young boy who wants to be a master of Chinese studies has been captured by English, which has changed the direction of life since then, just like a child who left home to understand the outside world and never came back. In 1995, I went to the United States, and I soon worked as an on-site interpreter in the immigration district court of the US Immigration Bureau (Manhattan) and the federal district court of the US Department of Justice (Lower Manhattan). I am glad that my English has come in handy and I can serve the vast number of new immigrants from China. I have never stopped my English study. I often remember English words at airports and long-distance bus stops by waiting for the bus and the plane. I want to learn more English knowledge, and I want to further improve my English, so I used my spare time to go to the University of Minnesota at Twin Cities and New York University to listen in on English, but I found that English teaching in the United States did not meet the requirements and characteristics of China people, and lacked the necessary explanation of language points. When I learned that Beijing Foreign Studies University had enrolled students, I resolutely gave up my job in the United States and went back to Shanghai Foreign Studies University in Nanjing, where I had been away for a long time. I believed in the gold content of the diploma of Beijing Foreign Studies University. I was too eager to charge, and I needed this diploma too much. I started my intense study in Beijing Foreign Studies University. I cherish this learning opportunity. Every time I hand in my homework on time, I attend face-to-face tutoring every time, and my grades are excellent. I often use the time when I go back to the United States to deal with things by plane to review my lessons and memorize words. After three years of study, I graduated with excellent results and wrote my bachelor's thesis, and I won the honor of being an excellent graduate. After three years of study, my English has made great progress. I can read a lot of original English books bought in the United States. I am translating an English book How to Write a Selling Screenplay, which will be published next year. Studying in Beijing Foreign Studies University has laid a solid foundation for me to study, live and work better in the United States in the future. The study in Beijing Foreign Studies University has left me a beautiful and unforgettable memory. Thanks to Beijing Foreign Studies University, my alma mater, because Beijing Foreign Studies University has deepened my feelings for English. Time flies, my youth is about to die in a flash. Looking back, I gave all my youth to English, and I have no regrets. If there is an afterlife, I will resolutely choose English, because I have an unfinished relationship with her. She has enriched my life, and she is worthy of my painstaking efforts. She has brought me endless fun. More importantly, she has given me a key to open the door of world civilization, opened a window to the world, and gave me a pair of eyes to see the world. The scenery outside is really good! * * Industry is good at diligence, and it is barren in play; It is a famous saying of Han Yu that "industry is good at diligence and waste at play", which means that the profoundness of study lies in diligence, while the waste lies in fun. The whole sentence means that learning is proficient because of diligence, but it is abandoned in laughter. Things succeed because of repeated thinking, but it can be destroyed casually. Throughout the ages, how many people who have achieved their careers have come from being good at work and being lazy at play. There is a good allusion that says the same thing. During the Warring States Period, Su Qin was ambitious at first, but because of its shallow knowledge, it was not reused in many places. Later, he made up his mind to study hard, and sometimes he read until late at night. When he was really tired and was about to take a nap, he stabbed himself in the thigh with an awl, and his blood flowed. He used this special method of "stabbing the stocks" to drive away drowsiness, cheer up and persist in learning. He finally became a famous politician. And "industry is good at diligence and lack of play" also shows that profound industry skills depend on diligence and hard work, and your grades will certainly improve, while you will accomplish nothing if you laugh and play all day. For example, technical experts rely on hard work and hard work against time to have such profound technology today. On the other hand, if you don't study hard, you will neglect your studies and achieve nothing. Therefore, we must keep in mind: "industry is good at diligence and leisure, and what is done is destroyed by thinking." Take our studies seriously and study technology hard, otherwise we will lose a lot. Be serious, be careless. Original: industry is good at diligence, and it is barren in play; What is done is thought, but it is destroyed. When the sages meet today, the fixture is finished, the evil spirits are pulled out, and the good spirits are worshipped. The rate of small good people is recorded, and those who are famous for their skills are all useless. Climb, scrape and polish. Guy was lucky enough to be elected, but there are many clouds but not many. All students can't be refined, and there is no ignorance of the department; You can't succeed if you suffer, and you can't suffer from injustice. Academic progress is due to diligence, while neglect is due to wandering and playing; The achievement of virtue is due to thinking, while the destruction is due to conformity. At present, the sage meets the sage, and the legal system is sound. Remove evil and evil, and be promoted to be handsome and kind. Those with minor advantages have been accepted, and those with skills are all appointed. Collect talents, screen, educate and cultivate them, scrape off dirt and polish them to shine. Probably only those who are lucky enough to be selected, who says that they are versatile and not exalted? You students are afraid that you can't improve your studies, and don't be afraid that the officials in charge of the department can't see clearly; I'm afraid that virtue can't be achieved, and don't be afraid that the officials in charge are unfair.
