Why you are wrong about everyone else.
Everyone is just like you… or are they? Have you ever noticed that people don’t always take the action or make the move that would gain them the most immediate ground, Perhaps then you might have determined that people don’t always have the same motives? Most of the time, most businesses have a similar motive, create the highest value for the shareholders.
But with individual people, victory at any cost might not be the goal. Or perhaps it is. Many people assume that everyone else is competing for the same result as themselves. Or that a majority has the same thoughts as themselves and sees things in our world in the same, or at least a similar light.
Everyone will define their own values and write their own rules. Many of them are not going to align completely with yours on all of the issues. But you won’t know that they are not on your side until the issue comes up.
