A Weird Life to Write About

I have had some very strange experiences in my life and I enjoy watching science fiction shows. It's no wonder that between the two, my imagination runs away with me at times. Maybe that is why I like creating stories. I have a dream that one day I will be a successful screenplay writer. How likely is that? At the moment, not too likely. I have to kick my own ass into gear. What am I afraid of?
Years ago I started writing a script for Star Trek, the Next Generation. I did it just for fun. I spent a lot of time on it and one of my aunts had noticed and told my mother. I hadn't said anything to anyone. It was just down time, an escape. But when my mother found out about it, she wanted to know more. I told her a bit about it. Her brother is in the entertainment industry and has written screenplays himself; she insisted that I show him what I had so far when I next came to visit her.
I did just that. He took the 20 pages or so that I had at the time and read them later that night. I saw him a day or two later... he said that I had a really good story. Of course he would, he is my mother's brother. He did say that my formatting was awful and he gave me a book on writing for television. It took me forever to reformat what I had so that it remotely resembled a proper format, but I really got into it. I wrote several more pages, not sure where I'd end up. A few more people showed interest... and some relatives were quick to point out that where I do not own the rights to the story, nothing would ever happen to it. No one would ever see it. I think I wrote about 60 pages before I dropped it. I still have a copy of it somewhere. Maybe one day I'll post it in a fan fiction site.
Despite not having finished that story, I always have one in my head. I actually did write an original screenplay. Now I need to proof read it and make some changes. Maybe I'll enter in a screen writing contest. I could have done that a while ago but I've been dragging my feet. Why? I ask myself that a lot.
