Before you plan your move, figure out theirs. Half of strategy is knowing what the other side wants.

Most plans are built around what you want and stop there, which is why they fall apart the moment another person is involved. Everyone is pursuing something, and if you know what it is you can often find an arrangement where you both get most of it. Without that, you are guessing, and guessing turns ordinary conversations into contests.

Before your next ask, spend five minutes on what the other person is trying to protect or achieve. Time, reputation, an easy week, not looking foolish. Then shape the request so it gives them some of that, and you will be surprised how rarely you have to argue.
