I'm definitely unemployed, but I do need to get things together.
No. Been down that road, it's even less easy than you think. The constant pressure to finish the book and market it destroys its quality, and you
will recognize it and it will not be a happy place you'll be in.
Writing is a craft. It makes you think about people and the world in more detail than most people ever bother with. It makes you grow as a person because putting them down somewhere, you start to understand your preconceptions and blind-spots for others, and are then able to transform them however you wish. That's not nothing.
You should absolutely write, as in give a bit of your day over to writing, every day. If you do that, you'll write. You'll finish books. They'll be better researched and better put together than if you try to make it your daily grind. People will want to read them, even if they aren't willing to pay, and that's still amazing if you think about it. To be a professional author straight out of the gate
is unrealistic and it will almost certainly not improve your situation. Whoever made 'hobbyist' a thing of shame in our culture is a moron.
If you're looking for a career, consider what the happiest or even just most well-developed characters in your book do. It's probably something you're passionate about but aren't willing to consider because you think it'll be harder than this. It isn't. I would say even
trying to become an astronaut is more realistic, because at least along the way you'll pick up a degree or two that you can apply elsewhere, even as just proof of "Hey, I have the attention span and commitment to become an actual real-life geologist, I can be trusted to do an unrelated thing like receptionist so that I have time for my family/writing."
Please don't force yourself down a path that's completely outside of your control to complete, and completely unnecessary towards the goal of
actually writing. [Edit: just saw how much of a necro this is. Since so many people are saying "Don't do it!" I stand by the importance of saying "Do it for the lulz."]
