Script progress

Its said that writing is rewriting. In that case I havent even started writing. I am working at an average of 45- 60 minutes per day on this script tentatively titled 'three' for the last 1 year. I did outlining for about 4 months. When I had an rough order of events from beginning to end I started writing the scenes. I would rough write (in my dictionary, a more thorough kind of outlining of scenes including dialogue) on some days and write the scenes on some other days. Now 60% of scenes are also over. I am not having much of the dreaded '2nd act jitteriness' may be because I have outlined well.
Hoping to finish the first draft by end of january 2009. I am not comfortable with brainstorming a first draft and then doing 10 rewrites. I plan a lot before putting anything on paper and consolidate as I move on. So I don’t think I will have to sweat much in terms of rewrites. May be one or two drafts that’s all. That too the main objective will be to cut down the length and compress it.
