In our daily life, we unavoidably come across various challenge now and then.

For me, the biggest challenge happens when I entered senior high school. I was shocking to find the physics teacher was teaching was totally beyond me. Thinking I just lacked a gift for physics, I stopped to making an effort and my grades were poor. Unfortunately, my teacher didn’t give up on me. Instead, he helped me analyse a problem and I realized I needed to rise to the challenge bravely. Now, I’m one of the top students in physics.

From my experience, I have learned that it is not our inborn gifts and our efforts that helps us achieve success. When we come across challenges, you should fight bravely instead of giving up.
