I've heard other people talk about it. Now I've done it, too.
I skimmed through my workshop notes for "Recycled Dreams" last night and today, getting a feel for the changes I want to make. I realized that, while I knew the background of the world, I didn't have a good grip on the characters themselves and what makes them tick. I started asking questions and what I discovered was pretty interesting (and raised some interesting ideas to explore in another story or two). I'll finish up asking questions and giving them the third degree.
My goals for the month are to finish this rewrite and submit it, and finish the first draft of "Alien Gurgitator."
