Today Jeff urged us to do what I think of as "pure writing": writing in a stream of consciousness style where you do not stop to edit, criticize, or reread what you've written. You take an idea and run with it, letting it play out as it will.
Admittedly, this is much easier with a solid outline and for an idea/plot/characters that have been living in your head for at least a little while.
I haven't had a chance to do much pure writing lately and did not do it with this challenge either. I am in a period in my freelance career that I have a ton of new cool opportunities that are taking nearly all my time and brainpower. When I do have a little "free" time, I spend that editing my first novel one last time so I can self-publish very, very soon.
However, I 100% believe in adding in this pure writing time, and it is a habit that I did for two months to complete both of my novels. I fully intend to return to this habit when I get my first novel published in the coming weeks to start on book #3.
My only pause is that I like to reach for a word count instead of a number-of-hours-in-a-chair goal. In two hours, I've cranked out between 2,000-3,000 words. Two hours of painfully trying to create perfect sentence after perfect sentence won't get your very far. Churning out a VERY rough draft of 2,000+ words can get you a finished first draft in no time :)
