College life is meaningful. I learned a lot in college. But I think the most important thing I have learned is self-study ability and critical thinking. Even if the major you studied in college may be forgotten. But the ability of self-study will accompany you all your life. Independent life has formed my critical thinking. It taught me how to think and make decisions independently. It gave me a correct outlook on life and the world. Anyway, college life is rich and colorful, and the above two points are the most important things I learned in college.
