As we all know, we can meet with various challenges in our life. Faced with challenges, how should we do?

Last month, our class climbed Mount Tai, that is more than 1,500 meters above sea level. Lacking exercise, I thought that this activity was great challenge for me. I felt very exhausted halfway that I wanted to give up. See this, my classmates and even some strangers encourage me. By the end, I managed to reach on the top of the mountain.

Therefore, don’t give up in face of challenges. If you are determined enough, it’s certainly that you can overcome it.
