I've started writing another novel. I'm still in the early stages - about 6,000 words in, but so far it's going well. I've done quite a bit of planning so I know more or less what will happen in each chapter, and can get on and write them relatively quickly.
This means short stories are on the back burner again, after a few months of writing and submitting them again (and a few welcome hits!)
I'm enjoying writing this novel. As with the last one, I find if I only have a few minutes, I can still add a bit to it. I leave my laptop switched on, and the document open (but saved) so it takes no time to get going again. With short stories, I need to have the whole story worked out in my head before I start to write, and I need a good couple of hours to get a complete first draft written. So unless I have a completely free evening, or half-day at the weekend, I won't start a short story. When writing a novel, however, as I can pick it up more quickly, I'm happy to add just a couple of hundred words while the dinner's cooking, or before heading off to Zumba class.
I know other writers who are the opposite - they can start a short story if they've only got ten minutes to spare, but need a couple of hours at a time on a novel, to re-read and edit the last section written, get back into the heads of the characters, and only then add more words.
What about you? Do you need a long stretch of time for a writing session, or can you make do with snatched minutes here and there?
