Writing is a Process

I've been working on a new screenplay, one which I think has serious commercial potential over the past few months. I started going down one road, then five months into it, I went down a completely different road. That frustrates me to no end, and there was a moment when I thought that maybe I should just forget about the whole thing. But the problem is, this new path was incredibly compelling and everyone I pitched it to was much more excited by it with the new twist rather than the old. Grrr. So, I took a break for a couple of weeks because I was feeling extremely burnt out with everything, then came back to it with a fresh eye. It is getting there, and I blazed through revisions of the middle sixty pages last week, but now goes the hard part which is the ironing out of the ideas and really polishing them. I drive myself a little crazy with my writing process, meaning, that I often find the story as I'm moving along, so the direction changes. This somewhat of a pain, but I found that this is the method that works for me. I used to try to outline and write histories, and blah blah, but now, instead, I sort of come up with a few plot points, and I typically know the beginning and end, then I start writing. Then I'll come up with histories as I go along. What a process, but I feel myself improving and growing with every new screenplay. Now I need to get back to this draft and really make it pop!
