If you've got an unfinished story, jot the name down on a list, (or if you're like me, jot down the theme, because the title is the last thing to put on it before posting!) and just keep looking for other projects you've wanted to finish.

It's not supposed to be difficult, so please, please relax. if you feel stuck on a story or can't remember where you put that file... say something, and I'll try to help.
