“For thinkers and all sensitive spirits, boredom is that disagreeable  “windless calm” of the soul that precedes a happy voyage an cheerful  winds.” -Nietzsche

In other words, don’t attempt to so fill your hours that you lose the  tine you have in boredom. Creativity springs from daydreams and  daydreams are born of boredom. Inspiration and not sloth comes of  boredom.
