We learn how to use both our desire to win and our empathy for those around us playing games as children. Games and having fun are the basis for all good strategies. Let us start with rats. Rats learn about the competition of life through rough-and-tumble play. When a larger rat plays with a smaller rat, the larger rat could win every time, but he lets the small rat win about thirty percent of the time. Why? Because if he doesn’t give the small rat a chance, the small rat won’t play with him anymore. Rats, like every other mammal, enjoy having someone to play with. The overly aggressive rat can no longer play because no one wants to play with him.
