No matter how confident, no matter how cocky, no matter how desperately you may desire to win, almost everybody loses sometimes -- even over important things. It stinks, but any time there are competitions, someone is going to lose. And -- most crucially -- every person is the main character of their own story. So being the "main character" should never mean a person automatically gets special treatment: if they're going to win, they should win for a good reason, such as deserving to.
