Self-discipline is absolutely important in today’s society, especially for college students. Compared with high school students, college students are comparative free to choose what to do and how to do. However, it is such a change that requires our college students to be more self-disciplined. 
在当今这个社会自律是非常重要的，尤其是对于大学生来说。跟高中生相比，大学生对于选择做什么、怎么做相对来说比较自由。然而，也正是这样的变化更加需要我们大学生自律。
Self-discipline is a key to improving ourselves. For one thing, without self-discipline, some college students would be distracted by other temptations, like playing games. To the contrary, college students will motivate themselves and learn something useful to improve their ability under self-discipline. For another, as college students are in an important period of forming characters and quality, self-discipline is indispensable for shaping them to be better. A college student who is self-disciplined will take his responsibility and try to be a better man. He will overcome laziness, greed and other temptations and focus on his way to be better. In addition, self-discipline will help him to be an estimable man in that a self-disciplined man will control himself to follow general rules or morals and avoid doing something harmful to the society and the public. 
自律是提高自我的关键。首先，没有自律，一些大学生会由于其他一些诱惑而分心，比如玩游戏。与此相反，在自律的影响下大学生会激励自己学习去学习一些有用的东西来提高他们的能力。另一方面，由于大学生正处于性格和个性形成的重要阶段，自律在让他们变得更好中是不可或缺的。一名有自律的大学生会抗自己的责任，做一个更好的人。他会克服懒惰，贪婪以及其他的诱惑，并专注于自己的方式变得更好。此外，自律会帮助一个人成为一个受人尊敬的人因为一个自律的人会控制自己遵循的基本的规则或道德，也会避免做对社会和公众有害的事。
In a word, self-discipline is very important and necessary, especially for college students since they are in a crucial period that determines their worldview and sense of value.   
总之，自律是非常重要和必要的，特别是对大学生来说因为他们正处于是在一个决定他们世界观和价值观的关键时期。
