I am new to Fung Shui and just finished the Essentials. I am working to situate my bedroom and office to face one my best directions. None of my walls face an exact best direction and angling the furniture does not work, so does it matter if we're off a bit on our best directions? e.g. My success direction is SE, so I positioned the head of my bed as close to SE as I could get -- it is between E and SE, but closer to SE. Is this okay, or does it need to be exact? Thanks!
