If people are rewarded for doing nothing, they do more of it. Eventually, they forget that doing something is an option. When the rewards stop, they sit and cry over their losses. Or they get angry and destructive and try to make somebody else pay for the injustice they imagine has been done to them. Meanwhile, the people who are willing to do something have to carry heavier and heavier loads to compensate. Always do a little more than is expected of you, and soon more will be expected of you. No wonder there are so many crabby people in the world.
