There are several aspects of improvement, such as intelligence improvement, vision improvement, emotion improvement, communication ability improvement and work ability improvement. Generally speaking, universities are a good time for self-transformation. In addition to these, there will be great changes, such as changes in appearance, changes in your own unique style, and things that you were afraid to do before can be done slowly and become more mature. There have also been greater changes in thinking. For example, the people you meet are good and bad, and some can make you grow. These are all great changes to yourself.
