Over at Edge of the American West, there's a good post and comment thread about the kinds of things people keep on their desks to make them write.
In the comment thread at EAW, people mentioned quotations, figurines, pictures, and, of course, the ever-popular terror inspired by a deadline. If you take as a given that time is part of it is time (see the 43folders post on Neal Stephenson), what makes you actually start writing?
I know I'm about ready to start writing if I get the urge to start rereading things I've recently published and things other people have recently published. At some level this seems reassuring, as though to say "you've done this before and you can do it again. Other people can do this, and you can, too." And despite my best efforts to use all the morning creativity I keep reading about, I am much more apt to start something and to find the real concentration needed if I work on it from late afternoon through the evening.
So is there a talisman, a quotation, a favorite pen, a mood, a piece of music that makes you get started?
