From where I stand, self-discipline is very important to college students for the following reasons. First of all, self-discipline can encourage college students to achieve their goals set in study, rather than give up halfway. Also, self-discipline enables college students to get rid of the sense of loss caused by the unfinished study goals and thus face life with a positive and optimistic mind. Finally, self-discipline plays an essential role in the future employment of college students. It can help college students overcome the difficulties in finding jobs.

In short, we should attach great importance to the cultivation of college students self-discipline, which is not only beneficial to college students themselves, but also conducive to the formation of a good social atmosphere.
