Give an inappropriate example, the difference between high school and college. In high school, for example, at home, your parents tell you how many points to take this semester, and if you fail, you will be beaten. University is when your parents tell you to study hard, if you don't study well, you won't be admitted to university in the future, you won't have a good job and so on. One is the task that must be completed, and the other is the expectation in my heart. In other words, in high school, someone took care of you, someone looked at you, and paid attention to the daily process. University just gives you a goal. If you want to finish it, study hard. If you don't want to finish reading, you can feel free, as long as you can graduate. Is to focus on the final result. Universities are liberal, but some people are in charge, but what is liberal? It is self-relaxation, mental relaxation. Whether you go to class or not, whether you learn knowledge or not, whether you skip class and sleep, whether you are addicted to the internet, fall in love, spend a lot of money, drink and smoke, and so on. What used to control your behavior is out of your control now, as long as you don't violate the law and discipline, just mind your own business. On the other hand, the relaxation of learning style is not limited to the classes taught by teachers, nor to the classroom. You can study anywhere and in any way, relying on your consciousness. As long as you do well in the exam and graduate easily, you will succeed. Therefore, the difference between high school and college is that in high school, you are a carriage of a train, and you run with it whether you run or not. You are not a locomotive. The university suddenly made you a locomotive. Run as long as you want and as far as you want. Nothing more than running well and learning something. If you run badly, you will degenerate and sink.
