Noone can ever achieve some success without failure，asfailure can usually help us learning what our strengths and weaknesses are.

WhenI was in high school，mostof my teacher and schoolmates thought it better to study science than liberalarts，sayingthat it promised a good future.I tried to follow this trend despite the fact Iwas not good at physics.It was only two months later when I failed an extremeimportant physics exam that I realized my talent lied in subjects like Chinese，English as well as history.I hadswitched to liberal arts immediately.

Thefollowing years witnessed my excellent school performance.But failure is not soterrible as we have expected as long as we can learn something from them.
