Like right now for instance. I feel the need to look out the window at the trees while I'm writing. In order to do that I'd have to switch my craft table and bins to the wall where my computer stuff is. It would probably fit, but there are other logistics involved. The main one is the TV, it's next to the computer and it fits there, plus the cable hookup is there. Although the computer desk and shelves would fit where the current craft stuff is, there would be no place for the TV. The TV often is on when we are surfing the "net." I know, it's the perfect "electronic" overload, right? I also like to watch movies when I'm working on crafts and then the TV would be behind me.
I hate when everything fits in a room and it leaves no room for rearrangement. My bedroom is like that. It's very small with just enough room to walk around the queen-size bed. So we had a bed with drawers custom built so we didn't need a dresser and the night stands are hanging on the wall so they aren't in the way of the drawers. No room for adjustment there.
So when I think about the computer/craft/hobby room being nonadjustable, I start thinking of how I could push the envelope; think out of the box; step outside the line. Then just trying to solve the problem gives my brain something to do and I feel better; albeit, frustrated that I can't look at the trees while I write.
Still, one never knows what will happen when I'm feeling blue.
