I used to be a child who loved learning and thought about how to improve my grades every day. But as time passed, I gradually realized that studying is not only for grades, but also to become a better person. One day, I finished all my homework at school and was ready to go home. However, when I walked to the door of my house, I found that my door was closed. I tried to push the door open but it was stuck. I'm starting to feel anxious because I haven't finished my homework and I have an exam tomorrow. I tried to call my parents but they were too busy to come home in time to help me. So I decided to solve this problem myself. I opened the door and found that the door shaft was stuck and needed to be replaced. I found some tools and started to repair the door shaft. In the process, I learned a lot about repairing and solving problems. After I finished changing the door axis, I went back to my home to continue my studies. However, I found that there was something wrong with the door again. This time, I learned how to fix it and successfully solved the problem. This experience made me realize that studying is not only for grades, but also to become a better person. Through solving problems, I've learned a lot of useful skills and knowledge that will help me better deal with various challenges in my future life. Although I need to spend some time and energy to solve seemingly difficult problems, these problems have made me grow and become stronger. So I'm thankful that homework helped me learn how to solve problems and become a better person.
