If your table is facing a doorway, walk path or corridor, make sure you have a mini partition to block the direct energies that may affect you. Corridors and doorway openings have a form of fast moving energy. There energies may distract you so that you can’t fully concentrate on your work. Make sure to have a small blockade or wall that ensures you can’t easily see the doorway or corridor infront of you. If it is your own business or office premise, you can put up curtains as well (simple and effective).
When you work in a cubicle type office setting - which means that your office set-up cannot be changed - you have to pay even more attention to creating (and keeping) good energy throughout your day at the office. While you might not be able to move your office desk into a feng shui commanding position or face your lucky feng shui directions, but there are still many ways to improve the energy of your workspace.
