I'm sad that it's too late to upvote this because this is GOLD!
I have such a similar story. I have an office in my studio and I hate that office, so I work from home. But I hate my home office - the energy sucks here.
You've just lit a fire under me. I'm tearing this office to bits RIGHT NOW and rebuilding it into something that ENCOURAGES creativity and focus rather than stifling it.
Thank you :)
