Determine what feels natural when positioning your files and equipment in your office. Do you tend to turn one way rather than another? Take a run through of your typical movements next time your reaching for the phone or a particular file and determine if it can be moved to ease the flow of your movements. Maybe a small desk-top file rack for papers and files you are currently working on can be moved to your right. This would save you time from having to get up and go to a filing cabinet to retrieve it when your ready to work on it. If you're right-handed, keep your phone to your left, leaving your right hand free for note-taking.
