You cannot choose what you are given, but you can choose how you make use of it.
Three years ago I failed an important exam in my life and became a student in an ordinary school. Disappointed as I felt at the shabby(破旧的) campus and the poorly-equipped classroom, I found the teachers patient and considerate(体谅人的). What’s more, I enjoyed the friendly atmosphere in class and therefore I decided to make the best of it. I worked hard and got along well with my teachers and classmates. Whenever I had difficulties, they were always available(有空的). Eventually, I became one of the top students in my class, which greatly increased my confidence and got me motivated.
My experience tells me that it is not what you are given but how you make use of it that determines who you are.
