There's a reason you act like you're the one calling all the shots. You're the chief, the big kahuna, the king of the hill. You're the man. Even if you're a woman, you're the man. Given everything you've had to put up with from whiny underlings, backstabbing colleagues and corporate jerks, it's a wonder you made it this far. You've earned this shirt and you intend to wear it every chance you get. When you walk around wearing it you're not "like a boss." You are a boss.
