When I was in college, I spent most of my time in the library except for classes, and my classmates could basically find me in a fixed corner. I also skipped a lot of boring classes. I really turned over a lot of messy things in four years. After graduation, I will basically spend one day in the library every weekend (except for traveling, I like to browse when the weather is good). I basically only read books in the library and don't do my homework, but sometimes I take notes. I like the atmosphere in the library. When you see everyone reading quietly, the sun shines on the bookshelf in the corner, and the years are quiet, it is really useless to pick a few books you like.
