My best friend says he'll never be a writer, "Because I always think that some won't understand or they'll disagree."
It's a trap to try to figure out the personality of your readers. Most of us know the age group or the type of people for whom we write. To attempt to be "all things to all people" is paralyzing.
I know writers who think that way. They're so careful to be orthodox, culturally correct, and not offend anyone, and their writing doesn't come from deep within. This is especially true of Christian authors. They don't have to prove their faith; they have to show their faith by opening themselves. When they're honest, even people who don't agree can accept them.
As I keep saying in this blog, I write from my heart and throw it out into the world. Not everyone likes my writing or agrees with my worldview. And I get criticized sometimes.
Here's one of my maxims:
I'd rather be disliked for who I am
than to be admired for who I'm not.
