I have joined the Story Telling Collective’s Short Story September with a view to improve my writing.

I have never done one of these before, so have no idea what to expect. Yes, it may well have been a good idea to do this kind of thing before I started writing my flash fiction, but I am not in the habit of thinking that far ahead and I suspect that I am not about to start now.
It is entirely possible that this is procrastination in disguise.
The one flaw I see so far is that it seems focused on fantasy writing as a genre whereas I am more interested in science fiction, but fiction writing is fiction writing, I just won’t be able to take advantage of submitting my short story to the Arcanist, which is one of the rewards for completion. I can live with that.
