First, delay. Procrastination is a bad habit of many college students, so many college students have made many plans, but they have never delayed according to the plan. Procrastination is still a serious problem.

Second, stay up late. Because college students have better physical fitness, they are more willing to spend their evening time doing some recreational activities, which will lead many college students to often stay up late, and then they may not eat breakfast or something, which will definitely have a greater impact on their health in the long run.
