I went on a trip to Thailand during the winter holiday, that was wonderful because I tried something I have never experienced before. One morning when we were walking along the beach, enjoyed sunshine, someone strongly advised that we went water skiing. However, we didn't dare to face the challenge because that seemed dangerous to do it. My friends all encouraged me, so I finally joined in them. At last, I couldn't stop screaming in fright. Later I felt that it was an amazement filling with fun. From an experience I learned that we should be brave enough to try something new. Only in this way we find a better self to meet any challenge.
