Variant 1: I like X but I don't know how to do X. So I want to write for X instead.
(e.g. I like comics but I don't know how to draw, so I want to write for comics.)
Variant 2: Writing for X must be easy since I see badly-written X all the time. How do I break into the X-writing business?"
X is typically comicbooks, film, television, videogames.
I think this is more of a "how do I get a job" question than a writing question. I'm not sure it's off-topic, but the answers are not about writing, they are about applying for jobs, finding creative partners, and advice on an entire industry.
What's the REAL question?
I think, often, what they are really saying is they believe there is a low bar for that kind of work so the writing "job" must be easy. The fact that they do not do X is a problem. They will not be prepared to write in service to the actual product. The only way they will develop that skillset is to do it. They also assume incorrectly that the final version is what the writer had intended, rather than a series of compromises and commercial decisions outside the writer's control.
The usual answers:
- Find an X and partner up.
- Submit writing samples to an agent or publisher.
- Try to make an X yourself
How I answer is "Try to make an X yourself. It points them in the right direction (where they will meet the potential partners and learn about the industry) and encourages them to write (which will answer a lot of the un-asked questions) rather than look for another person to give them permission to start writing.
The problem is that my answers get criticized for "not answering the question" because it is not directly leading to "getting a job".
I am encouraging the OP to write an X. He does not need to wait for a partner or outside approval, and those things will not magically materialize. No one will give him a job he is as yet unqualified for. By doing it, he is gaining experience.
I don't want to argue in comments about the legal issues of submitting unsolicited work to agents and publishers (most will not even look) – that's not how industry jobs work, but it's not my agenda to tear down other answers. That's what voting is for.
Is there a better way to handle these questions? I honestly feel they are partly "How do I get a job" questions, which I'm not even sure is on topic.
