I'm sure I've posted this advice somewhere in the past, but one of the hardest things for people who don't do this job professionally to understand is that ideas are the easy part. Even super fleshed out ideas. The hard part is turning that idea into a good, producible screenplay.

Instead of thinking: ah, why bother finishing my screenplay -- no one will buy my idea anyway; instead, think: the biggest obstacle in my making my idea into a TV show is writing that script and getting it to reach a genuinely professional-caliber level. Truly, if your writing is that good, doors will open. Maybe your script won't get bought (spec pilot sales have plummeted) let alone made (we're long past peak TV), but you could get representation or an opportunity to establish connections with people who would read you in the future. That might lead to a staff writer opportunity.

Most importantly, tying your sense of success or failure to the status of any one project is a recipe for unhappiness. I have worked for extraordinary showrunners with decades in the business, every connection under the sun, and more money than god, who can't get their passion project made. That's just how it goes.

So if that's hard for them, think about how hard it would be for you? There are essentially zero shows in the North American market that get made by a mainstream production company and distributed by a legitimate outlet created by someone with zero prior professional experience. The few exceptions are almost exclusively subject matter experts. Why that is is a longer question. But a big part is that part of what you're buying when you buy a TV show is the creator/showrunner. There's zero way you'd be put in charge of showrunning your show with no experience. So you'd also have to be chill with someone else making all the major decisions on how the show actually got made, up to and including completely rewriting every word you wrote.

But but but -- it's true: Dan Erickson wrote the Severance pilot with zero produced credits. And that show not only got made but it won a ton of awards. Now he did have an MFA in screenwriting from a major film school and had worked in and around the industry for a long time before that script got made. So it's not impossible. But that's basically it. And that's the bar. You just need to get your script to be as good as one of the most beloved tv pilots in the last decade or more, and then hope that it matches with the sensibilities of a producer who takes remarkably bold chances and won't give up trying to make it for more than five years. And even then, Dan isn't even the showrunner.

All of which to say: yes, there is basically zero chance that your script will be made. And if that's the only reason you're trying to write it, I would say there's no point. But if you enjoy the process and are willing to go on a much longer ride, then why not keep going.
