I'm writing about 1,200 to 2,000 words a day. Every day. The only thing that varies is the amount of time I have available. I work. Until recently I worked 2 jobs, yeah, 7 days a week. The only days off I got were national government mandated holidays. 3, almost 4 years of that. I still wrote every day, but not as many words at each sitting, a girl has to sleep sometime.
I don't do that anymore. Being in the habit of writing every day I can churn out my story like you wouldn't believe, because I acquired the habit.
