Worth this proposition is relative, depending on what it is compared with. If you think what you are taking or doing is meaningless to you, even if you don't travel, you will sleep or play games in the dormitory, then I think traveling is worthwhile. No matter what scenery you saw and where you went, you have accumulated social experience and enriched your experience. If what you are doing or the content of the class is meaningful to you, but you want to go out to play, I suggest you try not to take time off, or once or twice occasionally, because although traveling is more interesting and interesting to you, even after graduation, you may not have much opportunity and time, but for now, your most important task is to learn and grow. You can take advantage of holidays or winter and summer vacations to go out and play. Don't worry.
