We're moving cubicals in two weeks (while I'm on vacation). My name is on the floor plan, thankfully. I'll be close to a window, a major improvement from my current windowless room.
I think I feel much like you do. I need my blanket. I stop most days for coffee. I do enjoy the coffee, but I think part of the reason I keep going is because it feels very comfortable. It's a routine that's my little space. The coffee shop owner remembers me and says hi. The employees remember me. It feels like my place.
I've held three different positions at my company. First one I thought "I could see doing this until I retire." Then I wanted a change. Again, "I could see doing this until I retire." Then I couldn't. Now I think "I don't know if I'll do this until I retire, but I do think I could stay at this company for that long." My blanket has gotten a little bigger.
