It's actually a good thing that you didn't join the organization. You can read two more pages when your roommates are busy with meetings, watch a good movie when they are busy with club parties, plan your future path and do something you like when they are busy organizing activities.
brief introduction
How big is the social package capacity now! It can be an official WeChat account or learning to edit videos to make Vlog, or find a part-time job, save money, give yourself a chance to travel alone and experience another life. Or you can find an internship company in your sophomore year, do internships in advance and accumulate work experience, which is much more useful than joining the student union.
You should recognize the reality that a university is not only to experience, but also to accumulate its own value through experience. This society doesn't believe anything unconvincing. It mainly considers your value and how much value you can bring to it.
