One: increase your knowledge and improve your communication skills. I once heard a high school teacher say that a university is actually a "small society". You have to adapt to this place before you can adapt to the real world, otherwise you will be very nervous. This adaptation includes knowledge and the ability to communicate. The ability to see is to increase your scientific and cultural knowledge and ideological and cultural knowledge and improve yourself from the inside out. Communicative ability is to communicate with more people and accumulate experience in communication. I think people in universities are not as "simple" as high school and junior high school, and they can really accumulate experience.
Two: lies in the future work. Education is a very important thing, which can affect a person for a lifetime and determine whether your future life is good or bad. The higher the education, the better to find a job. This is an eternal law, and it is great to go to college. I once heard a passage (said by a mother): Son, I ask you to study hard, not because I want you to compare your grades with others, but because I hope you will have the right to choose in the future, instead of being controlled by this society; I hope you can choose a meaningful job instead of being forced to make a living. When your work is meaningful in your mind, you will have a sense of accomplishment and dignity. With a sense of accomplishment and dignity, you will feel happy.
