That said, spending hours working from your couch on weeknights or at your kitchen island on Sunday mornings might not be the most productive thing to do. Studies conducted by Alan Hedge, Ph.D. and CPE at Cornell University, found that a comfortable working environment can do more than make workers happy: It can improve productivity as well. Just like new workout clothes can motivate us to hit the gym more often, an office space with good feng shui can help us work more efficiently.
I suggest sitting in a chair, in each of the positions you mention, and seeing where you feel most “in charge” of your space. Without seeing the situation, I am imagining that the Command Position/window setup might be best, as you should be able to block the bottom half of the window so that your Chi energy doesn’t flow out the window. But your own sense of safety and power are what count the most.
Energy, or "chi" is one of the fundamental concepts in feng shui, and being able to increase the chi at your desk is important. More chi means greater prosperity and security for you, ensuring your success and happiness. Place an object in the wrong spot, and the chi is disrupted, and you will need to re-implement feng shui for the office desk at your office desk.
If you have been neglecting your work environment, take some time now to pay attention to the feng shui of your office, and we mean really pay attention to what is going on in your workspace. Answer some basic feng shui questions, such as, for example: What is happening behind your back? What do you first see as you come in? What is the quality of the air you breathe in? The quality of light?
