Hi,Blackiekitty,
I've tried to change the mountain of my front door using metal plates on one side of the door frame, but it did not produce the effect I wanted. Maybe I will try change the mountain with the help of a carpenter (He'll have to remove the door and put it back into place at a different angle).
With respect to your boss - I would check first if he's sitting in an area with good stars. If the location is very good, then it's not too bad to face a less good direction (the total loss direction offers the highest growth opportunities) but if you can have both then it's brilliant. I am not sure about this, but I think you can put an appropriate hexagram on his desk. But if West is his total loss area, then he's a West person and SW and NW are not the best directions as well.
Having a favourable hexagram above your office door can only do good. I changed my apartment door, it now faces my total loss direction (before it was only the frustration direction) but as it's the hexagram for wealth, I was able to discover where my abundance drained away (I got the period wrong). It may take it's time but if you're open to receive the hints then you can take the appropriate steps.
Love,
Astrid
