In the movie Ridicule, there is a quote that says, "Patience is the first sign of Nobility." I have found that the only reason I make myself to do anything is because of time constraints. You have to be at work at 6 or else you're fired. You have to have this paper in on the 21st or else you're punished. If I had a choice, I'd do nothing but lazy about in some kind of "fuck you" to the constraints of time. It as Errant says "Merely a way to check our own productivity." In a sense, it once again is one of the definitions of our own existence in a purely moralistically corrupted sense. We do not have to be productive in any capacity to have a fulfilled life. Cultural definitions of time make it so.
