"Pride makes people lag behind, modesty makes people progress" is my favorite motto. This is what Chairman Mao taught us. It means: as long as people are proud, they will fall behind, while being modest, eager to learn and not ashamed to ask questions can achieve better results! I didn't understand this sentence at first, but an experience gave me a new understanding of this sentence. I remember that in the third grade, under the guidance of my mother, my grades were not bad, especially in mathematics, and my grades were often above 90. Gradually, I feel proud. In class, the teacher was lecturing, and I didn't concentrate on the lecture, just a little gesture. The homework assigned by the teacher is only scrawled. I just watch cartoons in my spare time and don't review my lessons. The consequences of pride will soon fall on me! It was the mid-term exam, and the math paper was handed out. When I look at the topic, it's very simple. I did it three times, five times and twice. I didn't check it carefully, I just looked around. The next day, the test paper was handed out. When I saw it, I was dumbfounded, only 86 points. I remember the previous scene vividly, and this score of 86 was unprecedented at that time. It's all because I'm proud of a little achievement, otherwise how could I get this 86 points? I have to eat the bitter fruit of this pride. Pride is terrible! After that, I never dared to be proud. I listen carefully in class and don't make small moves. Homework is written neatly and often gets "excellent"! Ask teachers and classmates for questions you don't understand. Many things happen. I did well in the final exam and was rated as "three good students". I tasted the sweetness and my heart was full of joy! Only after this incident did I really understand the meaning of President Mao Zedong's motto "Pride makes people lag behind, modesty makes people progress". It is warning people to be modest and eager to learn, not to be ashamed to ask questions and not to be proud. I will keep this motto in mind and put an end to pride.
