I started writing when I was fifteen, and I just couldn't stop. Mostly written lyrics, but do have a few scripts under my sleeve. I am not a professional by any sense of the word. I write for more of a hobby and to get the ideas on to paper and out of my head. I've taken a few online writing courses and read multiple books on screenwriting.
Someday, yes, I would like it to take me places. But if it doesn't - I'm going to continue to write anyway.
