Hi Shuckins,
Don't know if my suggestion will do you any good. About ten years ago I was searching for a job. I saw an ad in the paper for "Technical Writer" and thought I probably had enough technical background and writing experience to jump in at entry level. Went for the interview and they suggested a technical writing course (part-time for 2 months). After the course I found a job. After a few years I went "free-lance." Freelancers often work from home. Since most companies you'd be associated with as a freelancer work during normal hours your workday is pretty normal.
If you have extraordinary skill at lavishing praise on products such as ordinary wooden toothpicks you might be able to become a "marketing" writer. I refrained from marketing myself. I want a good conscience about the things I write, lol.
Anyway, from reading your posts, you have clear written English and that is a major prereq. If you can figure out Aces High then you probably have enough of a technical bent I would think. Might be worth looking into anyway.
There are other kinds of writing opportunities too, but I would guess that technical writing might be more stable. Otherwise, until you build up a client-base for articles you run around like mad. Maybe authoring a textbook (or even editing) would be more along the line of what you'd be interested in.
There is one statement about writing that I've found to be true. "You write by the seat of your pants." In other words you may sit for a while before the cogs start turning. I remember reading somewhere that Hemmingway sometimes would struggle for a day, get 500 words down, then throw the paper in the trash. Course that's creative writing for a novel. Thankfully technical writing has many more boundaries that help quide your thinking.
Well, just an idea.
Best Regards,
Cement
