Secondly, I do not do this full time. Writing is part compulsion and part hobby. It is a brain break from the crazy shit I do for a living but I actually have a career that detracts from writing. If I am lucky I can squeeze out eight hours a week though I often don't even have that much time.
Last is my penchant for constant...constant...constant re-writing, re-editing, and revising. I have likely deleted half of everything I have written and my last word count was 89K. Yes 89K and I am maybe only 1/8th the way there. Maybe.
That said I am wrapping up chapter 4 which had been bothering me for awhile. Then again everything I write bothers me and deciding when it is time to stop and call it done is the hardest part.
