"Query: How contrive not to waste one's time? Answer: By being fully aware of it all the while. Ways in which this can be done: By spending one's days on an uneasy chair in a dentist's waiting room; by remaining on one's balcony all of a Sunday afternoon; by listening to lectures in a language one doesn't know; by traveling by the longest and least-convenient train routes, and of course standing all the way; by lining up at the box-office of theaters and then not buying a seat; and so forth."
-from The Plague by Albert Camus
This passage made me laugh.
