Three years ago, I became a student in an ordinary school.  Disappointing as I felt at the shabby campus and the poorly-equipped classroom, I find the teachers patient and considerate.  However, I enjoyed the friendly atmosphere in class.  I decided to make the best for it.  I worked hardly and got along well with teachers and classmates.  Whenever I had difficulties, they were always available.  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 determine who you are.
