I've slipped, but have been incredibly busy with writing. My goal was one story per two months, so don't feel bad, gettingby. I've only sent out one story I've written this year so far.
However... I spent weeks bogged down on one story going nowhere at the start of the year. Until I got it written, for better or worse, I just couldn't extract my mind from the tussle, to work on other things. Got that done, decided it was too bad to send out; to my mind, it just hadn't quite worked, despite all that time. But I think I learned stuff doing it. (I know you're not supposed to judge your own work, but there are times... maybe I'll take another look at that story in a year or two. Maybe. Mind you, it wasn't my worst story.)
The next story took about a month to write. Started as a short, but the plot opened up and it really needed to almost be a novelette. I don't know yet if it worked or not--I'm having a break from it while it awaits feedback. But part of my effort went into stopping it becoming a novel. So that never got sent out either. Yet I was writing heaps.
Then, I did a writing exercise in my writing class, which I warped into a sci fi story for fun, and it took me less than a week. That one got sent out. It's still getting sent out. It's got some near misses, so far. Which just shows that you can never underestimate a writing class exercise, because as you do it, you make it your own. It can be a great way to get ideas (depending on the class--mine is very much for the pleasure of writing, with a very accomplished teacher). The main thing I find is to not give a damn when you are writing, about what anyone else (even your critical self) will think about what you write. It doesn't matter. Let the muse muck around.
Recently, I realised my writing is making me unfit and weak. So I reinvented my fitness regime (i.e.: became consistent and adjusted it better), changed my diet to include more protein, good fats and less junk, and started getting to bed half an hour earlier at night. (Also went on holiday.) Two weeks into the new health regime, I had a day where three completely different stories developed in my head, and, I finished another longer short in a week. Things are looking up. I've got a queue of stuff to work on, and to edit. Seems like the new diet and sleep patterns are helping my brain out.
Anyway, that's what's helping me. At some stage, I'll make up for my lack of subs by sending a flood out the door.
