Few queries about scripts and other problems

I’m working on my first script that looks like I actually will complete it. My wife and friends ask me what I’m going to do with it when it’s done. I just tell them that I’m going to get the script done first before I worry about any of that. Cause on all of my other unfinished scripts I worried about all of that. It’s really putting the cart before the horse. My advice would to just write and perfect your script(this could take a year or more alone) then copyright, but don’t worry about anything after that until it’s time, it’s just extra stuff in your head that doesn’t need to be there while you’re consentrating on a script. Besides run a search on the internet, or talk to some people on this board and you can get alot of good ideas where to go next.
