re: Those of you who work from home, what are some musts for your office?

I have been working from home since the first of the year
I am set up in the living room in front of a big window looking into the yard (live alone)
Built in book cases next to window come in handy
I keep the tv on a music channel during the day for background noise

I learned real quick to have extra ink on hand, there isn’t a supply closet when you’re at home
