First of all, determining the direction is really the most important. In college, most students leave home, out of the long-term control of their parents, and are likely to indulge in it uncontrollably and get lost in the colorful campus life. The most common example is that after four years in school, I found that I didn't learn much professional knowledge. Faced with the choice of finding a job in postgraduate entrance examination, I found that my academic level was not enough, so it was difficult to go to postgraduate entrance examination. Besides, it is difficult to find a satisfactory job, and I lack professional knowledge and ability. Therefore, after entering the university, finding the right path before moving forward will pave the way for the future.
Secondly, improve social skills, expand social circles, broaden horizons, cultivate hobbies, explore more possibilities, and find out whether you have higher talents in unknown fields.
In short, these four years are a process of exploration, development and trial and error.
