Intent has been the hardest thing for me. I try to “get it right the first time” because when I find myself in the “editing stage”, I freeze. I don’t know what to change.
In school, where we learned drafting before final paper, I never did it. I’d submit my first, and then rewrite the drafts, and got marked down for not changing anything. I couldn’t “see’ what they were expected out of me unless they told me very specifically. I might change a few words; there’s analogous forms to every concept that I’ve ever seen, so that’s not _too_ hard.
Even then, things like, “Clarify?” didn’t mean anything to me. Even now, I don’t know what that means. I’ve had it explained to me but there’s no “click” in the head. Probably some mismatch in my brain / mirror neuron thing – who knows.
Then again, I remember 4th/5th grade the start of questions like, “What was the author’s intent?” and… I couldn’t answer those questions right. I could see situations where *all* parts of a multiple choice question _could_ be correct. Which was was “most likely?” I haven’t the foggiest. I still don’t. Oh well. That’s why writers often partner up with editors and such – a total DIY isn’t possible for everybody and likely it’s not for me either.
