In our daily life, we unavoidably come across many challenge now and then. I meet a big challenge when I was in high school. I was shocked to find which the physics teacher taught was totally beyond his understanding and I lost my confidence completely. Think I lacked a gift at physics, I stopped making efforts and my grades were poor. Fortunate, my teacher didn’t give me up. Instead of, she helped me analyze my problem and I realized I needed face challenges bravely. I regained my confidence, adjusted my approaches but worked hard. I improved my physics before long.
