Mine, said the stone,mine is the hour.I crush the scissors,such is my power.Stronger than wishes,my power, alone.Mine, said the paper,mine are the wordsthat smother the stonewith imagined birds,reams of them, flownfrom the mind of the shaper.Mine, said the scissors,mine all the knivesgashing through paper'sethereal lives;nothing's so properas tattering wishes.As stone crushes scissors,as paper snuffs stoneand scissors cut paper,all end alone.So heap up your paperand scissor your wishesand uproot the stonefrom the top of the hill.They all end aloneas you will, you will.

There's no question that positive thinking has a place in business. [...just as it has in the the rest of a happy, successful person's life.]

I like to think of the senses as having a volume control in the brain. The volume turns up on all the other senses when you lose one.
