One of our authors read in a book that you should "touch your work every day," meaning that you should keep the project you're writing in a place where you can find it, and you should sit down to visit the work each day even if only briefly, in order to move things along. I completely agree with this. Some days it feels as though all I can commit to is opening the computer file, but once I begin then the body in motion does truly tend to stay in motion, and often I keep writing. Science is cool that way.
But what is the source of the quote? In an online book search (including Amazon's nifty advanced feature) I got nothing when I hunted for it. In a regular search (Yahoo and Google) I came up with two websites that mention it, and a commenter attributes it to a magazine editor and author named Kurt Rheinheimer. Any other suggestions?
