Is your office setup meeting your needs, or do you feel frustrated by it?  The difference could depend on which side of your brain is dominant.  
The following was taken from Smead Organomics, "The Right-Brained Office vs. The Left-Brained Office":
Right-Brained Rationale
People who are right-brained have a creative flair, are strongly visual, and take a holistic approach to putting their office space together.  They use a lot of color and need to keep things in front of them in order to avoid the "out of sight, out of mind" syndrome which causes them to create piles instead of files. 
Left-Brained Logic
People who are left-brained dominant work better in a well-organized work space where everything has a designated "home" out of sight, and everything is in its home unless it is the task at hand.  They use a lot of numbered or lettered index systems for easy retrieval.
