I thought four years' experience in college was enough. Once, during an honorary university like the Presidential Scholarship, three good students and national scholarships were enough. But after listening to a senior's speech at the school commendation meeting, I feel that I am really far behind. I was in a university that was at the bottom of middle school. I thought I was the top student in our school. I thought my school limited my better development, but that senior is in our school. (He won 2 national prizes, 1 principal scholarship 1, 5 first-class scholarships and 3 SCI English papers, all of which were cited. ) So, it is only after 90 points that I know that 90 points is not easy. With these 90 points last semester, I came into contact with more excellent people, and realized that I could not be satisfied with the status quo and should work harder.
