Well, having come back from my holiday with an idea for a novel and a determination to have written the first draft before I go back to Zakynthos next year, I've decided to knock the short stories on the head for now (unless one is bursting to be told) and dedicate the next few months to the novel.
I must admit to feeling a bit daunted - I have only a moderate amount of faith in my staying-power. Having the attention span of a flea, I tend to get bored before I ever get to finish a first draft, hence my predilection for writing short stories.
Having attempted the 80K in 80 Days challenge this year and having observed other writers' progress with said challenge, I think I have a much better idea of how to write a first draft now than I did before.
