You don't need aggressiveness. You're already passive-aggressive, which is not any better than aggressive-aggressive. The answer is not to become a bigger bully

You don't need aggressiveness. You're already passive-aggressive, which is not any better than aggressive-aggressive. The answer is not to become a bigger bully to get your way more often. You need to learn how to argue persuasively. You also need to be right, it's not enough to have strong convictions, it's much easier to convince people and build consensus when you are (more) right or have a better answer. Or if you find out you are wrong, maybe you adopt the other person's perspective, not sulk away feeling put down. Either way, "winning" an argument means everybody wins, not just you got your way. Believe me, unless you work for and with only idiot politicians, people notice and don't care for obnoxious loudmouths. If they're always winning when you think they are wrong, you either do in fact work in a horrible political organization, or you are just wrong (AND probably work in a horrible political organization).
