The true character of a champion/solider is not revealed by his/her reaction to victory; however, it’s by his/her reaction to defeat.
Champions/soldiers realize that losing a game/battle is only one aspect of an entire season/war. In sports and in war, you always have many contests and skirmishes. What you can’t afford to do is throw in the towel after being unsuccessful in some of those instances.
Therefore, allow the champion/soldier in you to be resilient, rise up, and bounce back from any defeat or loss you may have suffered because ultimately it’s not over until it’s over.
