It should be a truism that you always give the client what he or she wants, but sometimes it’s extra-difficult. Not to say that clients are picky, but, well, let’s just say that clients are picky.
Although sometimes vendors can be, too. As a case in point, I remember a magazine that I worked on that needed an illustration of a slice of pizza. Not a difficult thing to draw, and there are reference materials everywhere if one suddenly does not remember what pizza looks like. And we would have taken any kind of pizza – supreme, pepperoni, veggie, ham and pineapple, spinach and feta, double anchovies – whatever.
But the illustrator we often worked with came back a few days later, no illustration in portfolio, and informed us that he couldn’t do the assignment because he was a vegan, or some brand of vegetarian that would have nothing to do with milk products, and couldn’t bring himself to draw cheese.
We were miffed. First, that he hadn’t told us sooner about his cheese-drawing aversion. There were any number of professional illustrators in the area who had no such qualms. Second, because we weren’t asking him to eat pizza or buy pizza or something else that might reasonably have caused him qualms by supporting the pizza industry. Just a simple black-line drawing of a slice of pizza. You couldn’t even see the cheese, really. You just knew it was there. But apparently even that was too much for him. But we knew what we wanted. We wanted cheese on our pizza.
Sometimes you do have to wrestle with your conscience to fulfill certain jobs. I edited for a religious client for many years, whose religion I did not espouse. I came to terms with it. As far as I could see, I didn’t have to believe the beliefs I was writing about; I just had to respect them, understand them, and make them intelligible and appealing to the readers. Whatever else I believe, I believe that religious publishing companies should not restrict themselves to only like-minded believers in their hiring. And yes, I wrote for them too, on non-doctrinal topics like charity and more official ones like prayer services.
Many freelance writers and editors and even the occasional illustrator must make these decisions – whether what the client wants is something you feel comfortable giving. In general, my advice is to suck it up and do what the client wants.
To use a trivial example, I stand firmly behind the Oxford comma, but if my client’s style guide doesn’t, out it goes, no matter how much it pains me. In those cases, the style guide wins. And the client.
Writing for children can be the most difficult assignment of all. Clients who assign writing that will go into textbooks are the worst. They specify not just story length, but also reading levels (there are programs that calculate this in any number of systems – use whichever your client likes), grammatical forms (e.g., dental preterites), and even phonics examples (two words per paragraph with diphthongs, for example). Then try to make the writing creative and engaging.
One set of children’s stories I worked on was a doozy. Instead of word count, the client wanted 15,000 characters-plus-spaces (a measure I had never heard of, but fortunately Microsoft Word has). Then there were nine separate characters, each of whom had to play a role in every story. There were other requirements, too. An abstract. Pull-out quotes. Illustration descriptions. Not to mention specific topics. And a schedule that required a story every five days. And I did it all, thankful for the work.
I have blogged about writing children’s stories before (https://wp.me/p4e9wS-cD). One of the things I said was:
I believe that requiring writers to abide by rigid rules makes it less likely that the story will be appealing. And if the story isn’t appealing, I believe it is less likely that the children who read it (or are supposed to read it) will get anything from it.
But that’s not my call. It’s the client’s.
First, as anyone will tell you, read the publication. And that means more than just the How to Submit page and the rates they pay. If you have a touching story about how your darling Muffin passed away, don’t send it to every magazine with the word “cat” in the title. Cat Fancy, for example, is about registered breeds of show cats. You’d be better off sending it someplace like I Love Cats, which pays very little but will give you a byline to wave in the next editor’s face. Likewise, if you have an article on how to select a vet or home remedies for ear mites, don’t send it to a publication that already has a monthly column that is written by a vet.
Since then I have lost the ability to work full time, or in an office. Or even in a burger joint where I’d be required to stand all day. My skill set is solidly in the field of writing and editing, and those I can do from home, on my own computer and schedule. In my pajamas.

What I do like are food game shows: Chopped, Iron Chef, Guy’s Grocery Games, Beat Bobby Flay, Top Chef, and so on. They provide the combination of food preparation, competition, and a reality show that demonstrates a real talent that satisfies my needs.

I have been an editor. I have rejected lots of manuscripts.
That’s not to say that you won’t need a professional (or at least semi-pro) editor at some point in the writing process. But in order to get your manuscript – anything from a blog post to a novel – ready for a wider audience, you need to give it a good edit.
