I did five minutes of free writing. I figure that's what I'll do when I don't feel like using a prompt or working on whatever is out there. It will keep me going and sometimes may suggest ideas or approaches I have missed.
One of the prompts I looked at the other day gave me an idea for my fat attack story. Take off in another direction, unrelated. Use it to show other parts of the character, perhaps unexpected aspects. I want to let the thoughts swim around in my head a while before taking the piece out to write.
