GREAT post. I am reading a lot about writing at the moment. I have read Stephen King's "On Writing" and that is what persuaded me that I could try NaNo or Indy this year. I may not be able to schedule regular time but I *am* managing to "bang out" roughly 1000 words per day. They may not be good words and are only a first draft of the only fiction that I have written longer than a school 'story' essay but I am getting into the habit of writing 1k words per day. Come rain or shine or illness.
With time maybe I will be able to write good words and edit the first draft into further drafts - or throw a draft away and start again, of course. Maybe one year I will be practiced enough at this writing lark (like I used to be in my teenage years) to attempt the full-on 50k NaNoWriMo. One day I may even get a short story published! Yeah, I am not holding my breath, but it is giving me something to work towards that should fit within the shape my life is these days.
