Selfish people are everywhere. Universities provide knowledge, ideas and skills, but they can't guarantee that everyone can think of others selflessly! Moreover, the more knowledgeable people are, the smarter they are, and sometimes they are too eager for quick success and instant benefit, losing their pure and enthusiastic side of being a man. The so-called exquisite egoist. Since ancient times, there has been a saying that every dog killed is a scholar. Of course, words cannot be absolute. There are still many high-quality people in universities, but selfishness is inevitable. Selfishness is human nature, but some people are generous and others are stingy. This has nothing to do with selfishness, but the difference in vision and mind. Sometimes in life, don't care too much. You may just care too much when you ask this question. This is not good. Let us open our hearts. In college, we should not only learn knowledge, but also learn broad vision and broad mind!
