I can't write in the apartment I share with my other half (the place is way too small), so I have to write out in the wilds of Manhattan. I joined a writers organization, a big loft space downtown where I go to write; I can go 24/7. You don't get your own desk -- you take what's open -- so I lug all my writing stuff around in a backpack and set up each time. My current favorite desk is in a little dark corner, a small pocket away from traffic, and I'm sitting here now. Other writers are around typing, hearing them is almost comforting. I don't know what I'd do without this place.
I also have a favorite café where I go to write in the mornings before work -- it's surprising how much I can get done in the noise, because the back room gets very crowded! They have the best mochas, which helps the writing immensely.
One of my fantasies is to get a bigger apartment -- you know, the kind with more than 2 rooms? And then we'd have a "writing room," and I could have a desk that's always ready and waiting for me, decorated and set up however I want. Or even an apartment where we could fit
a desk... no room in this place, I'm afraid. One day...
Or maybe it's better that I don't write in the apartment. That way, I'm physically separated from my nemesis, the TV.
