A man who has something on stake is always more worried, thinking what others will say. What will happen if he loses today. They think of their fame, that stardom but they forget that they're losing against their opponent mentally. A person who has nothing to lose only goes into give his best shot at the chance he has got. It is either win or lose. If he wins, he is a champion. But if he has lost, he won't be mentally broken. He will get up and try again.
