Secondly, about dreams, I basically didn't have dreams when I was a freshman, and I was depressed that I didn't have dreams every day. . . Now I feel that I need to be realistic, and my dreams sometimes don't need to be so far away. For example, you can dream of 600 points in Band 4. Learn to be practical, even utilitarian, and you will not be too depressed.
Finally, about self-control and persistence. I think going to college is not only about learning knowledge, but also an excellent opportunity to change your personality. For example, I never cleaned the room before, but now it is the cleanest in the whole dormitory. The same is true of self-control and persistence. Exercising this will for four years will certainly be of great benefit to you. . .
