That's a nice milestone, and it goes all the way back to my short bursts of writing in the mid 90s which produced the first 5 stories. Since I got serious about writing at the beginning of 2006, I've written 35 stories and substantially re-written 4 of the early 5.
More importantly, I've finished as many stories (20) in the nine months since Viable Paradise as I finished in the time before Viable Paradise (21 months of seriousness + time for the early 5). If nothing else, that stat right there shows how Viable Paradise caused me to take my writing to a new level.
My next goal is to have finished 50 stores by the time I attend the Lincoln City workshop in early September. That's essentially a story a week. Guess what I'll be doing starting July 1!
It's also time to get those stories out in the world, but that's another whole ball of fear I'm slowly working on conquering.
Write. Finish. Revise. Submit. Doing great on the first two, it's the second two that need work. That's the other goal for early September: have most of those 50 out in the world, looking for homes. Scary stuff. But very, very necessary.
Keep moving forward. Don't look down. Onward.
