By re-arranging (or straightening up) your work area periodically, you may:
• find things that have appeared lost or have "fallen between the cracks"
• establish new ways to better organize your work
• find yourself unexpectedly stimulated with some fresh, new ideas
• feel like you have a "fresh start" toward what you are trying to accomplish
Tip: Whether you rearrange your office or just make time to take stock of what you are doing and how you are doing it, the process will provide you with fresh insights. The likelihood is also high that you will become more effective and re-energized towards the task at hand. Why not give it a try!
