I like to write spec fiction like young adult urban fantasy or adult urban fantasy (urban fantasy just means it's set in modern times, but there's usually some type of supernatural element, whether it be magic or superpowers or just slight superhuman abilities or the like). I've considered writing books about spiritual things and healing, but I'm not so sure I want to be tied to that. While I'm well studied in theology, religion, spirituality and such, that's something that gets tricky with people. And everyone who's writing in those fields is writing in such a way as to say, "My view is correct and I know it for sure." And people generally want that, too, because they're usually reading for answers to make them feel less shameful or anxious. Knowing answers makes a person feel more secure emotionally (but it actually just represses the shame and anxiety, usually). So if I were to write that type of thing, I'd constantly be saying, "There's this possibility, this possibility, and this possibility, and there's really no way we know can know which is accurate. I tend to think this one makes the most sense from what I know, but that's just me, and I could be wrong." Few people want to hear that. They want the writer to be authoritative and sound like he's got all of the answers so they can attach to him like a father-figure and take up his beliefs (at least, that's how a LOT of readers are and they don't know it). So my writing would likely piss off most people since I wouldn't give them answers in the typical fashion. lol And the people that disagreed with the things I presented would be ticked off too and start claiming I believe what's in my books even though I'm stating in the books that these are just possibilities and that I can't know which, if any, are accurate. Then Christians and who knows who else would slander me (and this is all assuming I actually became known--lol). And what if I find new information and all the old stuff I write is obsolete and inaccurate. I can't take back what I wrote. I can only write again and disavow the old stuff. lol I'm not so sure I want all of that possible drama in my life or my family's life.
And besides, in the East they say, "He who says, does not know. He who knows, does not say."
In other words, when someone really knows the truth, they'll keep their mouth shut about it, because they'll realize that a person must experience it for their self, so there's no reason to tell anyone. It can't be properly conveyed. Better to just enjoy life and let people do their thing. So if I ever reach that point, I'll be like, "Oh great, I wrote a bunch of meaningless books. Oh well..." LOL
But if I write fiction and put some interesting deep meanings in them that people might consider exploring, now that's fun. And no one kicks up too much of a fuss on that stuff.

And it's a lot of fun to write, too. The other is kind of boring. Interesting, but boring. And I feel like I'm arrogant or prideful if I write spiritual or self-help stuff. lol So who knows...
I'm writing about a guy right now who has multiple personality disorder and his main three personalities have slight superhuman powers. He works with the police, but he's also killing off some pretty horrible people at the same time, or at least getting them killed. It's dark and a little comical. It's a TV show I'm writing into a book. Should be interesting, I think.
