You must be positive. It's a natural law of The Universe. If you don't be positive, bad stuff will happen to you. You will feel bad, and since not being positive builds bad luck, each negative thing you do, say and/or think will cause you a negative situation: It could be something as small as someone having the tiniest bit of yellow on their teeth. Or something as big as someone going to hell and continuously being raped up the butt. Bad luck.
