There's a great story in today's New York Times about the the writer Roxana Robinson, and how she leaves her well-appointed office to sit in a sparse spare bedroom in order to really get writing done:

Yesterday at brunch, four of us — three writers and an artist — were talking about our various methods, tics and needs that must be accommodated in order to get our brains to cooperate and the words to come. Music, no music. The time of day. The type of room and its brightness and configuration... We sounded like insane people.
Personally, I like a small room, with my computer up close to the wall, essentially making me a horse with blinders — when I was writing my book, I pushed my desk into a small walk-in closet, which worked out perfectly. Sometimes music helps, but it must be in a language I don't understand, or else songs I know so well that I don't focus on the lyrics.
What's your trick or favorite spot? What do you do to make the words come?
