I am a professionally trained actor having graduated from the American Music and Dramatic Academy, in New York. From there I was introduced to screenwriting via Jason Chaet (Remember, Putzel)
Before that and still I am also a playwright and try to write in as many formats as possible.
If it's genre specific, it depends on the mood I'm in. I love every sort of genre and plan on writing in all of them.
I believe that the rules and knowledge we learn are not strict but tools we can use to best service the story we are trying to tell.
