In order to better understand people's views of the world, a researcher once placed two children, one a pessimist, and the other an optimist, alone in separate rooms. The pessimist was placed in a colorful room full of all kinds of imaginative toys...the optimist was put in a room filled with horse manure. The first child played in the room for a little while, but soon came to the door asking to leave, because the toys were boring, and because they broke too easily. Likewise, the young optimist soon came to the door...but rather than asking to leave, she asked for a shovel. Of course, the researcher asked the child why she wanted a shovel. She replied, "With all this manure around, I know that there must be a pony in here somewhere."
