Boredom is essential.

It is the sin that believes in nothing,cares for nothing,seeks to know nothing,interferes with nothing,enjoys nothing,hates nothing,finds purpose in nothing,lives for nothing,and remains alivebecause there is nothing for which it will die. -Dorothy L. Sayers, "On Boredom"

Only the most acute and active animals are capable of boredom. -- A theme for a great poet would be God's boredom on the seventh day of creation. -Friedrich Nietzsche
