Failure is common in our life. No one can avoid them. When we fail in doing something, we often feel very depressing. Sometimes failure can make us lose hearts. So no one is willing to fail. On the contrary, success can bring us sense of pride. If one enjoys his continuous success in his career, he will have confidence to himself. Therefore, failure is the mother of success. A failure doesn't mean one can never be successfully. Those who are always afraid failure will never succeed. In a word, as long as we can get some lessons and experiences from our failure, we'll be sure to succeed.
