Going to begin filming

So today will be the first day of filming, I have only half the script done but I'm confident that the rewrite of the script was better than the old one. Although I don't plan on filming everything in order, because that would be very stupid, I have downloaded a movie making software that will help me put together all the scenes so that I don't have to film in actual chronological order. I've contacted everyone I'll will be filming and asked them to meet with me as soon as possible, although I didn't exactly the setting I wanted, I obviously don't have the resources to get everything the way I visualized so I'll have to make do with what I have. I really excited to start filming, I've really enjoyed this whole process and can't wait to see how my final product comes out. But I'm a little worried about time, December draws nearer and I don't want to run out of time, because filming is only half the work, I also have to put everything together and edit, to see what fits together or what to keep or throw out.
