How are you going to deal with the psychological impact of the transition from your own boss to working for someone, on-site, following full office hours?
I've almost never worked from home, I've always worked out of my own office, shared an office with another freelancer, or worked from coworking space. And I've also always kept a pretty typical ~9 to ~6 schedule Mon-Fri. So I'm not sure those things will be a huge adjustment?
