Whether to sign up or not depends on you. The decision is in your hands. If you think you have time and interest, you can apply. It is best to sign up for a club or organization in the university. You can not only enrich your spare time, but also cultivate your own ability, not only in literature and art, but also in organizing if you work as an officer in the literature and art department. College life has a lot of time to squander, not as tense as high school. There is nothing wrong with singing narcissism. How can others like to listen to songs that they can't stand? I don't even know what the selection criteria of your art department are. Since you really want to enter, and the literary and art department chose you to sing too intoxicated, then you should not be so intoxicated, naturally.
