There are winners and losers in this world.
When a person is winning he/she will be happy. However, winning can’t last. At some point the person will have to start losing. Call it a law of nature. Now he or she will be unhappy and miserable.
And there are others who know that at some point in their lives they will both be winners and losers. This much is guaranteed. Such a person will remain balanced in both the times of happiness and adversity.
