You will learn an important lesson today. But will you learn from it and use it tomorrow?
Winning isn't everything, but wanting to win is absolutely essential. After all, if you don't have the desire to win, how will you rise up the ladder in life? You don't have to come first every time; often, coming second or third, or even last, is enough to lift you higher and closer to your goal. If you don't want to win, how will you inspire yourself to move forward? Inspire yourself with a worthy goal and aim to win.
Stay true to yourself and be ethical. Let unethical people dig their own graves; don't play their game. Rise above their petty squabbles and take the high road.
