I just received a promotion, but I have some concerns over the office. I have a wrap around U-shaped desk. The credenza runs the entire width of the back wall which is also a window. The door is on the end of the opposite wall. So when I sit and face my computer the window is to the right and the door is to my left and behind me. If I turn to the left to work on my desk, my back now is towards the window. I have always been told not to have your back to either the door or window. How do to combat this bad chi? I can't rotate the desk, because it is too long. Please help.
