Personally, I think it is very necessary for those people to change their personalities during their college years, because our society is relatively open and free now. If we are in society, we will always be very introverted. It's hard to get a foothold in this society unless your family can arrange a particularly good and stable job for you, and one day you need to go out into the society by yourself, which is very difficult, so in college, we should not be so introverted, we should change our personality, and it's easy to change our introverted personality in college, so I suggest you change your introverted personality here. We must overcome our psychological barriers, such as not being nervous when it's time, and getting up. For example, you can join a college student union or a school student union, so you will often participate in some activities after joining the student union. If you are ruthless, you can make yourself more cheerful. If you meet some more open classmates, you will definitely use their influence to play with them. Only in this way can we change our introverted personality and become cheerful and outgoing. To tell the truth, in college, we need to cultivate our social skills, rather than introverted teachers studying alone. It's lonely. In this way, we can't feel the happiness and happiness as a college student. To tell the truth, in the water, we must learn how to be an interesting person. We also need to know what to say, who to meet and how to speak. This is very important, and it is also an important knowledge point for us to enter the society in the future. Before entering society, we must learn how to deal with our social skills.
