After turning off the computer, there is always a letter from a student in my mind: teacher Kaifu: I will graduate soon. Looking back on my so-called college life, I want to cry, not because I left, but because I learned nothing. I don't know how to write my resume. If I am used to it, I will leave it blank. Perhaps the greatest gain is ... patience and adaptation to nothingness ... This letter expresses the feelings of many junior and senior students. During college, many students indulge themselves and waste time, but many students still can't find the right learning direction. When they were awakened by the first make-up notice, when they received the first rejection letter from the company they applied for, these students were surprised to find that their future was so slim that it seemed that it was too late to make all efforts ... This "fourth letter" was written for those college students who hoped to wake up from ignorance as soon as possible, those who had never been sleepy and hoped to grasp their future and destiny, and those future college students who were about to enter the university threshold. In this letter, I want to say to all my classmates that college is the most critical stage in a person's life. From the first day of admission, you should have a correct understanding and planning for the four years of college. In order to enjoy the greatest happiness in study and find a job that you like when you graduate, everyone who has just entered the university campus should master seven kinds of learning: self-study, basic knowledge, practice integration, interest cultivation, initiative, time control and dealing with people. As long as these seven points are well done, the biggest gain for college students when they graduate will never be "patience and adaptation to nothing", but "confidence and desire to have everything". As long as you do these seven points well, you can become a happy graduate with potential, thought, value and prospect. University: the key to life University is the key stage of life. This is because entering the university is the first time in your life to put down the burden of the college entrance examination and start chasing your own ideals and interests. This is the first time for you to leave your family life and participate in group and social life independently. This is the first time that you no longer simply study or recite the theoretical knowledge in books, but have the opportunity to practice it yourself while studying the theory. This is the first time that your parents no longer arrange everything in your life and study, but have enough freedom to deal with all kinds of problems in your life, study and control all your time. University is a critical stage in life. This is because this is your last chance to receive a systematic education in your life. This is the last time you devote yourself to building your own knowledge base. This may be the last stage in your life where you can spend a lot of time studying, or it may be the last stage where you can have high plasticity and constantly correct yourself. This may be the last time you learn how to be a man in a relatively tolerant and ideal environment. University is a critical stage in life. At this stage, all college students should seriously grasp every "first time" and make it the cornerstone of their future life; At this stage, all college students should cherish every "last time" and don't let themselves regret it in the near future. After four years in college, everyone should try to weave their dreams, make their own direction clear and lay a good foundation. We can use the following figure to describe the position and value of university in one's life for four years: We can see that university is the time when one's learning ability changes the most, and it is an important period connecting the two stages of "basic learning" and "stepping into society". Therefore, for four years in college, we should strive to cultivate our learning ability, improve our learning realm and make ourselves a person who is good at lifelong learning. Four years of college is only once for everyone, and four years of college should be spent like this. ...
