You're one of those people who thrive on deadlines and competition. The more pressure there is to perform, the more you like it and the better you do. You like opponents.
They give you something to push off from, something to compare yourself to and compete against. Even in the closest relationships, you don't mind arguing and fighting; it makes you feel alive. As difficult as it may be for your partners, for you the road to intimacy is paved with quarrels. You're not one to fear that a relationship is over just because you've had an argument -- far from it! You enjoy the fight, but not nearly as much as you enjoy kissing and making up. And once the fight is over, it's over. You don't drag through the same territory again and again. This need for engagement and competition makes you a natural for one-on-one sports, all types of athletic events, martial arts, or any other activity where your body is as engaged as your mind. You tend to prefer things that are simple and straightforward and can't be bothered to try to keep up with convoluted or confusing people. You know where you stand on matters and can hold your ground.
