From The Thief of Time

“Wen considered the nature of time and understood that the universe is, instant by instant, recreated anew. Therefore, he understood, there is in truth no past, only a memory of the past.  Blink your eyes, and the world you see next did not exist when you closed them.
Therefore he said, the only appropriate state of the mind is surprise. The only appropriate state of the heart is joy. The sky you see now, you have never seen before. The perfect moment is now.
Be glad of it.”
