And bear in mind that, when you're sending a script to a producer or a TV station, you're asking them to spend a lot of money on filming it. Be sure that you've given them a reason to want to. An alternative to jumping straight in with a feature film script might be to begin smaller, perhaps gathering a portfolio of published articles and short stories to impress people with. Just one thing. I know it sounds stupid, but presentation does matter.
Readers are human, too.
But now that the industry has become so fragmented, there are increasingly fewer really busy places where you can expect to find that sort of a job. But then if you're put off by remarks like that this is the wrong business for you. Everyone does it differently - and there ain't no easy way. Try everything, and don't give up. Any experience is useful.
