Moira Allen has a great article on "submitter's block."

Allen writes, 

        

"You want to write, but you don't. Or perhaps you start, but can't bring yourself to finish, leaving a dozen promising articles or stories in various stages of incompletion. Or perhaps you finish, but can't quite bring yourself to stuff those pages into an envelope and pop them in the mail. Your family,      friends, or critique group say your work is wonderful. So what is holding you back?"
