I know that pain is the most important thing in the universes. Greater than survival, greater than love, greater even than the beauty it brings about. For without pain, there can be no pleasure. Without sadness, there can be no happiness. Without misery there can be no beauty. And without these, life is endless, hopeless, doomed and damned. Adult. You have become adult.
Harlan Ellison
The more often we see the things around us - even the beautiful and wonderful things - the more they become invisible to us. That is why we often take for granted the beauty of this world: the flowers, the trees, the birds, the clouds - even those we love. Because we see things so often, we see them less and less.
Joseph B. Wirthlin
