For your rectangular office, the optimal desk placement adheres to the command position principle, allowing you to see the door without being directly in line with it. Place your desk in the northeast corner of the room, facing southwest. This position offers excellent support from the solid north wall behind you, symbolizing stability and a clear path forward. To enhance focus and career growth, incorporate earth elements like ceramic desk accessories or a potted plant. For colors, consider earthy tones such as light browns, yellows, or soft greens to foster a grounded and productive environment, balancing the wood element of your desk and the natural light from the south windows.
