Okay there is still lots of steps to go, but...
I finished the first draft of my screenplay/book. Of course in my head - it was finished a long time ago. It's already a movie, playing for an audience of one.
All those years of it being in my head, haunting me, and now it's all out on the page, and on a flash drive.
I feel relieved, but a bit daunted by all the steps still to come. I will worry about all that later, today I am just going to bask in a sense of accomplishment.
