Ddl is a buzzword in universities. Its full name is deadline, which means deadline, especially all kinds of tasks to be completed in universities.

First of all, I declare that the emergence of ddl is inseparable from procrastination. Here, I hope everyone will face up to ddl, which is the product of procrastination and heavy schoolwork, and is no different from the "deadline" for handing in homework on time in middle schools. Ddl is like a messenger. If ddl is not eliminated, the bad news will become good news, and we will move from laziness to self-discipline.

Investigation shows that the prevalence of adult procrastination is 15%~ 20%. The most affected by procrastination is college students. About 36%~45% of college students have obvious procrastination, and 46%~50% of them will keep procrastination. When students enter the university from middle school, the campus environment has changed greatly, and the study pressure has been reduced unprecedentedly, while college students with low self-control are prone to procrastination.

The typical performance of procrastinators is academic procrastination, and the affected students generally have a persistent desire to delay their studies. More than 30% of their daily activities are spent on procrastination, such as sleeping during the day, playing computer or mobile games, watching TV and surfing the Internet. Academic procrastination and poor task completion, as well as the resulting depression, social anxiety and self-limiting behavior are mutually causal, which has a serious impact on the physical and mental health of the delayed person.
