Three years ago I failed an important exam in my life and became a student in a ordinary school. Disappointing as I felt at the shabby campus and the poorly-equipped classroom, I found the teachers patiently and considerate. Besides, I enjoyed the friendly atmosphere in class. I decided make the best of it. I worked hard and get along well with my teachers and classmates. Whenever I had difficulties, they were always available. Soon, I became one of the top student in my class, and which greatly increased my confidence and got him motivated.
My experience tell me that it is not what you are given but how you make use for it that determines who you are.
