"The Theory of Trash Circle by the Senior Sister in 'The Fool Who Sleeps'"

It really impressed me. Looking back at myself, I was limited by the mediocre circle in high school. I thought I was hardworking every day, but I was actually just satisfying myself and being self-indulgent. I was satisfied with being in the top 30 of my grade and thought that was my limit. After entering university and interacting with classmates from different backgrounds, I realized that "the sky can be as high as the stratosphere". Even now, I am still surrounded by various mediocre circles. I haven't even formed a mediocre circle yet, I can only say that what I do is purely for self-entertainment.
