Donna Barr posted a few things on Facebook recently about being a hack, which she says is a good thing. I tend to agree. Work is work, after all, and 99% of what we all do is not Great Art or Great Literature, as the case may be.
Decades ago, Harlan Ellison wrote the introduction to a short story in a collection of short stories. He said that he'd hated the character, hated the story, hated the resolution, and sold it to a magazine he didn't normally do business with... but he made 3x as much money for this as he would've otherwise. His final paragraph of this brief exposition was "Moral of the story: I may prostitute my art, but at least I'm not a cheap whore."
John Ciardi once wrote:
See the poet.
The poet is fat.
The poet is fifty.
The poet is making a living."
There is no sin in hackwork. It pays the bills. Sometimes, rather handsomely.
