Welcome to Steemit. Sounds like you're pretty busy, and pretty ambitious, with all that you would like to accomplish. I've experienced the writing novels and not finishing them. I've currently got two (one that probably needs a major rewrite) that are not quite done. Fortunately, though, I also have two others that I did finish and self-published for Kindle. So, it is possible—if you have time. And with kids, time will always be at a premium. I wasn't able to write and finish mine until both our boys were out of high school and my work schedule was such I could work on the novels more.

It sounds like you've got a lot of different interests to post about, so I wish you well. Getting out on posts where you feel comfortable commenting is probably the best way to be 'seen', meet others, and kind of "demo" how you write and what you know. I highly recommend it for anyone, but particularly people just starting out. It'll help build an audience. It's not a fast track, but not much here worth doing is. :)
