Three years ago, I became a student in a ordinary school. Disappointing as I felt at the shabby campus and the poorly-equipped classroom, I found the teachers patient but considerate．Besides, I enjoyed the friendly atmosphere in class．I decide to make the best use for it. I worked hardly and got along well my teachers and classmates．Whenever I had difficulties, they were always helpful. Soon, I became one of the top student in my class, what greatly increased my confidence and I got more motivated．My experience tells me that it is not what you are given but that how you use it that determines who you are．
