One. It's about psychology. As a college student, I think self-reliance wants to express more about self-judgment, making choices and making decisions by myself.
That is maturity and stability. Think like an adult.
Second, it is inevitable to talk about the economy. Be as independent as possible. Many college students choose to do odd jobs part-time. Do some manual work to earn some extra money, and also do some mental work to earn money. Learn some skills, such as PS, editing, photography, etc. Learn to manage money, make some financial products, and invest to earn extra living expenses. I remember reading it.
A passage from Professor Sun of the University of Hong Kong
Universities should get up early, have breakfast, run professional courses, listen to public courses carefully, read their favorite magazines, take a nap at noon, participate in a club activity or play basketball in the afternoon, take a walk with people they like at night or go to the study room to read quietly.
Society does not need to learn hegemony, nor does it want to see students give up their studies to start businesses. You just need to read the university book list fluently and completely, find your loved ones and interests, read books that can enrich your thoughts aimlessly, meet a few good friends, exercise or shape your body to refine your professional knowledge.
You are good enough to do these things and have spent the past few years in college.
