First of all, you should know your financial situation like the back of your hand and spend rationally. For example, if your parents give you a semester's living expenses, you should plan your own consumption. Many students 1 month spent three months of money, and didn't know how to spend it until there was no money. It is suggested to prepare a small account book to record how and where they spend each sum of money.
Secondly, for their own investment, including perseverance exercise, broaden their horizons, physical and mental health, during the university, they can master 2-3 sports that they are interested in and good at, which is of great benefit to the future social life. If you don't know anything, how can you find the same language as others? In addition, good health is the capital of struggle.
Good luck.
