If I spent it in college, let me talk about my thoughts (that is, when I assume I will start over)
1, professional study: As we all know, universities have greater freedom, and the management of teachers and schools is very loose. If it is a military school, it must be strictly controlled. On the other hand, if it is a key university (such as 2 1 1, 985), the study pressure will be very great. So if you want to enrich yourself, the most basic thing is to learn your major well first. Be careful in class, and you can find some books related to your major after class.
2. Contact with society and practice: University is also called semi-society. Ordinary universities are full of all kinds of people, so you should get along well with teachers, classmates, roommates, alumni and so on. Simply put, no matter what kind of people they are, you can play well with them. (A little glib, I don't like it myself) But you should learn to deal with all kinds of people anyway.
Social practice, it depends on what kind of idea you have. For example, let me talk about some phenomena in our school.
First open a canteen in the dormitory to sell all kinds of snacks.
Second, buy yourself a printer, and print and copy for students cheaply.
Third, wholesale some jerseys in some jerseys wholesale departments and then sell them back, such as the Champions League and NBA.
Fourth, of course, you can also go out and find a part-time job, sell mobile phones, tutor, distribute leaflets and so on.
3. Love. Personally, I think universities should talk about falling in love. This is the best training ground for love, which will let you learn a lot about love. Besides, girls in universities are simple. Look at these girls outside the society now, who don't want a car or a house. If you are lucky enough to meet your life-long travel companion in college, congratulations. It is said that many of my high school classmates met their girlfriends in college.
4, physical exercise, needless to say, do more exercise when you are free. Now that they are looking for jobs, those companies have to look after their health.
5, other knowledge and skills, if you have a computer, it is best, the most basic, computer office software should be able to type quickly. If you are interested, it would be better to master some computer hardware knowledge. Other aspects of computer, such as CAD, graphics, video editing, web design and other computer-related software, are the best to learn. (You can do it without proficiency, but you should be able to operate in the general direction.)
Also, regardless of arts and sciences, you can read more books, such as some entrepreneurial and inspirational ones. Of course, there are some world literature masterpieces, and it is good to know more about them.
That's about it, but it's too difficult to do the above. You can practice selectively according to your own situation. This is my experience, I hope I can give you some help. Manual only.
