Is your desk a mess? One way to overcome a messy work area is to place items in relation to their usefulness. Items you use all the time should be at arm's length. Things you use rarely, like reference materials, can be stowed on a shelf across the room. Only have files close by that you use all the time, the rest can go in a file cabinet.
Besides reducing clutter, you are sure to have the things you really use close at hand.
Are items in your workspace organized in relation to the frequency of their use?
