Now the question is which of these ideas in my head is the next headline?
I think it happens to a lot of us.
I know one discussion in the past is that some writers didn't want to give people ideas. My argument has been that just about anything we can come up with has already been done somewhere by someone. I have, for example, tried to come up with unique ways for villains to kill their victims but I think just about everything I have come up with has been done. I'll think, a-ha, he/she can kill this person in this manner that's never been done before and pat myself on the back for my originality. And then I'll search online and find a real case where someone did killed someone that same way.
That said, I do have a planned trilogy that I've had on the backburner for several years now. Part of the reason for putting it on the backburner is that some of the issues might have been touchy sixteen years ago when I started it. Wasn't a good climate for it, I didn't think. And now? Well, a large part of the backstory is stuff that happened politically around this time and beyond. Sixteen years ago, it was conjecture. People would be like, well, sure it could happen but it probably won't. But after this year? It actually could. Some of the stuff hasn't happened (yet) but given the current political climate certainly could and I'm not sure I'd want some of the ideas out there. Sixteen years ago, I would have been fine with it because it was in the distant future and something that I thought could conceivably happen but hoped would not. But now, even though I'm sure people have thought of it and who knows if people are plotting to do such a thing, I don't know that I want to have some of those ideas out there. In the story, it's basically the good people doing things to the bad people but, in reality, in today's environment, there's a very good chance it might be the exact opposite.
So, still on the backburner . . .
What typically happens to me is that I start writing things and, before I finish them, a book or a movie very similar to it comes out. Like I have another story I started sixteen years ago and, basically, the main character's backstory is a movie that came out this year. This happens often enough I sometimes feel maybe I need to wear a tinfoil hat to keep my thoughts contained. LOL. Of course, it seems to be the unfinished stuff that ends up in this situation. Doesn't seem to work for the stuff I actually finish and publish.
