Have you ever met someone who changed your life in a meaningful way? For me, that person is my high school politics teacher, Mrs. Jie. Mrs. Jie was always patient and caring. She would stay in the classroom long after the bell rang, answering questions that student don't comprehend. To help us understand boring and complex theories like "supply and demand," she used funny stories—for example, comparing market competition to a basketball game between classmates. "If you keep practicing," she said, "even the hardest concepts will become clear." Her words made everyone feel inspiring.. The most memorable moment happened one winter. I scored only 72 on a politics test which was my worst result. As I stared at the paper, my face burned with shame. During lunch break, I hid in the empty classroom, tearing the test into pieces. But Mrs. Jie found me that I didn't have lunch. She sat down and quietly taped my paper back together. "Look," she pointed at a multiple-choice question I got wrong, then reviewed the whole test with me together. She showed me how to underline keywords in questions, a trick I still use today. With her help, I began studying differently. Every evening, I rewrote my notes in colorful pens and tested myself with some cards. Two months later, I scored 98 on the final exam. When Mrs. Jie told me my grade, she clapped for me with her proud smile on her face. Mrs. Jie taught me that failure is just a paused step, not the end of the road. Even now, whenever I face difficulties, I hear her voice saying, "Just believe yourself and try."
