One day, when I was on our way to school, I was asking myself whether it would be better to stop persuade myself that I could do well in my weak subjects? Wouldn’t it be easy to give up math and physics? Just as I was thinking about this, I come across my teacher, with who I often discussed my problems. He gave me some suggestions and taught me several method of addressing my problems. In end, he said, “Keep it up!” From his words, I sudden realized that if I don’t give up, it will always be someone to help me. Because of my teachers and my family is always supporting me, I have no reason to give up.
