My favorite writing form, for a long time, was the short story. I wrote them for years before attempting a novel. I also wrote poetry, but not as much.
I've been working more on book-length manuscripts in the
past ten years or so, but I still write short stories from time to
time. Especially when I have just finished a novel that has taken a lot
out of me, or when a book hasn't turned out the way I'd hoped, or when I
don't know what to write next. In a way, short stories are a sort of
home base for me. I keep returning to them.
What is your writing "home base?"
