From politics to the workplace, from the petty grievances of neighbors to the heady disputes of presidents and prime ministers, all too often the game is zero sum. My gain is at your loss, throwing me under the bus is how you overcome. But it doesn't have to be that way. We can get to yes by uncovering common interests instead of exploiting each others weak spots. The people you think are in your way don't need to be jumped on, rolled over, kneed in the face, or have fireballs hurled at them. Because some ways of winning cause us to lose a little bit of ourselves with the victory, and eventually you'll have won too much to have anything left to lose.
