As an IT man, how should I plan my life?

As a bitter child who has been addicted to computers since the senior grade of primary school, let me give you some advice. If you don't study what the teacher teaches now, you may not even have a chance to go to college. A good university is quite different from one, two or three universities. If your teachers and classmates communicate with each other in and after class, it will be more difficult for you to study your favorite major by yourself than in a university with a stronger academic atmosphere. In addition, writing code is not a skill, and neither is installing a system. These skills can be learned in a short time. The knowledge and experience that need to be accumulated for a long time, the understanding of computer systems, and even further understanding of natural science, are not something you can understand by learning 100 programming languages. Believe me, although there are many drawbacks in the education system, what you have learned is not useless except for exams. There is no useless knowledge, just don't know how to use it. If you only study knowledge for exams and learn programming for writing codes, you will be useless in the end. As a programmer, a programming language is always a method, not an end. Learning a language is to realize algorithms, that is, people's ideas. This is the soul of a program, and you can't understand it by learning a hundred ways to write Hello World. As a technology, when you learn a language or use a system, or learn Emacs and Vim, there is nothing to be proud of. It's just a tool Just as many cutting-edge technologies and theories can be learned from reading papers, few authors put forward these theories in the papers, but this determines the gap between people. Learning to use knowledge comprehensively requires a lot of knowledge accumulation and experience. So I suggest you study hard and go to a better university. Some professors are called "masters" for no reason. They have rich experience and accumulation, which is much better than those who only teach for an iron rice bowl. And if one day you suddenly feel that you can connect all kinds of knowledge from childhood to college and weave the original classified knowledge into a huge network, that kind of happiness will never be brought by money and reputation. So, shift the focus of your life from computer to study. In addition, it is still too early to talk about majors. Although I am a computer major, I prefer the math department. Not very interested. But as a professional course, you will have all kinds of pressures to learn math well. Although computer courses are also important. But to be honest, if you pay attention to this aspect from now on, there is not much room for you to improve in four years. But there are several computer courses that must be easy to learn and understand. In addition, the knowledge of mathematics brings much more benefits in in-depth research than those computer courses you just fool around in the past. Maybe you don't know the purpose of those differential equations and probability functions now, but you will understand them one day. Sometimes learning is like moving bricks. You don't know what this boring, repetitive and endless job is for, but if you don't move, you will never stand on the built tower and overlook your knowledge castle.
