I think it's probably safe to say that everyone out there has a movie script or book idea. In fact when I took a look at doing a 101 in 1001 a couple of years ago, I was surprised and perhaps a little dismayed at the large number of potential authors out there. All of a sudden it seemed that everyone shared the same dream, and my own little ideas were tiny, tiny things in the veritable sea of words out there. That kind of thing puts me off, as I do like to at least think i'm doing something unique, even if I'm not. However, more and more it seems to me, understanding more about the process of being an author (rather than having an idea to write), that there is a huge difference. Everyone out there has a story to tell, but not everyone writes it. We no longer live in a world where the 'idea people' are deferred to and valued. Ideas are a dime a dozen these days. Being a writer means actually putting words down on paper, being productive, returning time after time to add more and more until you have enough to start editing in to a finished article. This is something I can really get behind, something I really want to do. I've had several ideas simmering away behind my eyes for the past few years and it's time to let them face the light of day.
Blogging is antithetical to being a writer according to Robin Hobb, who wrote an excellent article on it here. I can see exactly what she means, but coming from a 'not yet writing something each day' mindset, I am going to try and either blog OR write something daily from now. Not always going to be possible, lots going on in RL atm, but i'd say as long as I get something written 3 days a week for an hour at a time, that's progress from the current zero hours per week. It's the writing regularly thing that's the most important to get part of my routine I think.
Finished the first 1500 words of my asoiaf_exchange fic yesterday. Was a little daunted to start with, never having written a fanfic before, let alone specifically for someone else, but I think it's going ok so far. Should be well finished before the deadline so plenty of time to edit and tweak before hand in.
