Some folks have it, some don't. Those who have it would be devastated if it were ever cut off. They think that those who don't have it are somehow inferior. They think it gives them power.

If you're not careful what you do with it, it can get you in big trouble. It has its own agenda. Somehow, no matter how good your intentions, it will warp your behavior.
