If there is any single factor that makes success in living, it is the ability to be benefi

ted by defeat. Every success I know has been achieved because the person was able to analyze (分析) defeat and actually learn something from it in his next undertaking (从事的工作). Wrongly taking defeat for failure, you are sure indeed to fail, for it isn't defeat that makes you fail; it is your own refusal to see the guide and encouragement to success in defeat.

Defeats are nothing to be afraid of. They are common incidents in the life of every man who achieves success. But defeat is a dead loss unless you do face it, analyze it and learn why you failed. Defeat, in other words, can help to get rid of its own cause. Not only does defeat prepare us for success but nothing can cause within us such a strong wish to succeed. If you left a baby grasp a stick and try to pull it away, he will hold it more and moro tightly until his whole weight is hung up. It is this same reaction that should give you new and greater strength every time you are defeated. If you make full use of the power which defeat gives; you can compete with it far more than you are able to.
