Do you organize things as a means to an end? Or is having things organized the end in and of itself?
Some people simply find comfort the order and safety of an organized world. Disorganization and clutter bother them intrinsically, even if it doesn't necessary matter. Like a pile of papers that needs to be organized even though it will ultimately get thrown away.
Others just organize because they know it makes them more efficient towards their other end goals. These folks have found religion in the “once of prevention is worth a pound of cure” adage. They organize not because they care now, but because they know when it comes time to extract value down the road, the work to organize now will pay off in spades.
