Nowadays, we have to meet many challenges either in our life or in study. Sometimes we win and sometimes we fail. However, there are two kinds of people have their own ideas about how to face failure. On one hand, some people tend to think that they have no capacity to do things when they fail at first attempt. They become pessimistic and unconfident. On the other hand, some hold the view that without failure,they will never succeed, so they never give up even if they fail several times. They keep trying until they succeed. As far as I am concerned, I prefer the positive and optimistic attitude towards failure. There is an old saying is "Failure is mother of success". Many stories of scientists and inventors such as Edison can prove this. Edison who had invented bulbs had failed more than one thousand times.He still didn't lose heart, but learned from failure and got final success. Therefore, if we don't make mistakes, we'll never get further progress. Failure always goes before success. We fail, fail and finally succeed. In a word, life isn't always smooth. Don't give up, come on! Success beckons on those who persist and learn from failure.
