    Failure comes to us sometimes. Last term, I met a painful failure, and it helped us find a new self. Before the final exam, I have promised my parents that I would get the best marks in all my subject. However, I did not listen to my teachers careful in class and paid little attention at my homework. As result, I failed two of my most favorite subjects, math and physics, which surprised everyone. Look back, I realized that it was my overconfidence which led to my failure. Only if we are modest but work hard will we have the chance to achieve our goals.
