Failure is a common thing in one's life. Almost everyone experiences failure in his life. When one fails in his attempt in doing something, he often feels upset. Some people may yield to failure and flinch from it. But others will stick to and achieve the final success.
Success is what everyone expects. It may lead to fame and glory. When one succeeds in doing something, he gets so excited that he often neglects all the unsuccessful at tempts he has done.
As the old saying goes, "failure teaches success." it is true that failure is an important factor toward success. The way to success is full of various difficulties and obstacles. Many important inventions or discoveries were achieved after hundreds of failure. And only those successes which have been achieved after many failures are really valuable and praiseworthy.
