Your objective is to compete with others to win. In your mind, the saying 'participating means winning' is for losers. Competitions are created to find one winner because in the end your result is measured in comparison with others. There is no one but you who knows the real taste of victory. Since you compete to win, you also tend to participate in competitions where you feel more likely to win. Sometimes it might not even matter what you are competing for - but it's a mere fact of comparison that excites you. People like being in teams with you, because you take the competition to a completely new level, infuse passion into it and make sure the victory is getting celebrated accordingly.
