This past week, I've had a modest goal of writing 500 words on my short story a day. I haven't reached that every day, but I've generally come close - with the exception of one day when I was just utterly work-slammed and didn't even get to touch it. I'm estimating this is going to be about a 7000 word story, which is where most of mine tend to fall. I'm about 2500 words in and on good track to finish in time to do a bit of editing before I post it for the FWO challenge.
The joy of writing every day is hard to express. It can be frustrating when I can't quite figure out the sequence, have to stop and puzzle something out, worry that there's not enough foreshadowing, doublecheck to be sure I have sufficient description without stopping the story cold ... but oh, the delight of the flow of words.
I know my writing time and energy will decrease again when I'm in school, so I'm pondering short projects that I can finish quickly. One thought I had was to do a piece of flash fiction, micro fiction or even a poem every day based on a sparker, such as the word of the day or a random Deviantart / Elfwood picture. I'm certainly open to suggestions of a good source for quick inspiration! (Weekly may be more realistic; I'll have to think about it and experiment.)
