The writing studio.
“If you want a room to write in, just get a room. Don't make a big production out of it. If it doesn't leak, has a window, heat in the winter, then put in your desk, bookshelves… chair, and start writing.”
— Natalie Goldberg, Writing Down the Bones: Freeing the Writer Within.
Room & desk: On loan from a friend for three days. It's enough.
