There's no better way to make sure you DON'T endear yourself to agents, producers, or writers than by spitting on what they do.
I'm not saying every screenwriter must live in Los Angeles. I'm saying every TELEVISION writer must live in Los Angeles. Until you bite the bullet and move, you WILL NOT BREAK INTO TV.
The absolute best way to network in the industry... is to GET A JOB IN THE INDUSTRY. If you're not working in the industry, you stand almost no chance of breaking in.
