I am averaging 4-5 new screenwriter questions every day from my web site. They are sending out scripts that aren't ready. They write a first or second draft and then send it out. Those scripts can't be ready. Screenwriting is rewriting.
New writers are in too much of a hurry.
New writers don't spend enough time learning the 'business' of screenwriting. New writers are realizing the importance of writers conferences in the scheme of things. These conferences are networking Heavens. A great place to pitch their latest script. Something fresh and new.
