Over at Wyrdsmiths, Eleanor Arnason asked if there were things you, as a writer, feel comforted by or "need" to write. I thought about this question while I avoided writing (cleaned the dining room floor, changed the fish tank's water,) and I decided that what I need to write is a window.
As I noted in the comments, I've worked really hard over the last several years (particularly when I made the switch to becoming a full-time, stay-at-home writer,) to not NEED any talisman to write. I've trained myself to work at any time in any place. That being said, I think there are things that make me work better -- a rainy day, a cat on my lap, tea in my cup, and a window to glance out. The window, I find useful, in particular because when I'm composing I often look away from the screen to organize my thoughts. I think I think better when I get a look into the neighbor's kitchen or to rain drops spattering climbing rose stalks or something at least mildly pleasant (the snow melting, etc., although currently all the snow that's left are those horribly filthy black chunks.)
This is, of course, a luxury -- one provided for me by the fact that I can write at home, near a window. I wrote large chunks of several novels in a basement office cubicle, so, clearly, I don't NEED these things. But when I have them, they make the writing process more pleasant.
How about you?
