In the Hindi scriptures, it is written that "Victory and defeat is part of life". I mean if we accept our defeat in mind, then we lose. And we do not need any competitor to lose, but our disappointment is enough. The man's nature has been invasive since the beginning, under which he has to win and when he loses, he does not acknowledge that defeat and falls into the deep well of despair. By the way you have written a good post.
