I came to the Department of Mathematics as an undergraduate, and I realized that the gap in IQ between people is bigger than that between people and pigs. The Department of Mathematics is really not a place for people to stay. I can say without hesitation that I was the hardest student in our Department of Mathematics when I was undergraduate. As a result, in a class of 60 people, I could not even be in the top 30, the most excessive. It was my roommate who copied my homework every day. In the last analysis course, he passed 90, and I got 60. Then I understood, it’s no good, it’s really no good, so I honestly transferred to financial mathematics, and then The road goes smoothly. Whether it’s gpa or Shenyan or looking for a job, it’s very good, and the salary is also very good. But I really envy those students who continue to go on the road of mathematics and then read the Ph.D. That is my dream that was out of reach. Every one of them is pure and pure in my eyes. I am really very Envy them. The first place in our class was a girl. Later, she went to a well-known overseas university to study for a Ph.D. She may not be very beautiful, but she is really smart and confident. Later, when I was studying metalworking, I met many beautiful girls, but they were not as good as this girl. Smart people really have a special charm. I envy her very much. I want to be a person like her, a person who contributes to the development of mankind in mathematics. It’s a pity that I don’t have this possibility when I’m already 30. I can only make up for it in another way. I married her home.
