First of all, you should make a scientific and reasonable plan. University life is rich and colorful, so you should think carefully and prioritize. I think professional study is still the most important, so we should concentrate. After studying, you can participate in various club activities. Of course, you should choose according to your hobbies and see what your purpose is. If you just want to increase your social experience, you can focus on your hobbies. If you want to work, study and support yourself, you can choose paid activities or jobs that you are good at. Personally, I don't recommend paying too much attention to economic benefits during college. After all, I am in the charging stage. On the basis of focusing on my studies and increasing my experience, I still need to pay due attention to making money to support myself.
Maybe some college students are financially strapped and want to rely entirely on themselves, and don't want to embarrass or burden their families. Congratulations, you are mature and independent before others, so the next college life may be very bitter and tiring, but you will gain substantial, rich, mature and experienced, but under no circumstances can you relax in reading and studying!
