That said, I have no idea of what will happen next in the spec market. Stay true to your vision. Opportunities will arise for the talented. Don't blow them. Okay, so Mr. Bigshot Screenwriter just sold a million dollar spec.
Writers can build lasting careers on one success.
Though I just heard it's the Hollywood job that people return to the least. Not for lack of trying, but the fact is, there are a lot of qualified screenwriters out there. I guess that is promising for those looking to break in. Once there, make sure your movies get made, and made well. Most of all, just be smart about it.
