Writing Spec scripts

To get an agent (which you must have) you must have at least two fabulous spec scripts of differing genres. A spec script is a sample script - one that you write "on spec" which will probably never get made, but which serves as a writing sample.

Which introduces you to the first rule of writing for TV - you will do a lot of writing that you never get paid for.

Yes, this is wrong. Yes, writers should get paid for their work. But to break in you must prove you are capable of TV writing, which is a very specific sort. To prove that, you must write. You must dance for the powers that be to prove your grace. You must cook a gourmet meal and expect no recompense or even a tip.

There's even unpaid writing you have to do after the powers that be (aka TPTB) do come to love you. Even if you're commissioned to write a script and a price is agreed up, $x for the story, $y for the first draft, $z for the second draft, and so on, you'll end up doing far more drafts than they pay you for.

So just get used to this idea right now. Later on, if you make it, you will get paid far more than most writers ever dream for your work. But for now, you toil without pay.
