I think you and I are a lot alike in this way. I have so many different hobbies, and in order to make any decent progress on any of them, I can only focus on one or two at a time. Today has been a Writing day for me as opposed to an Art day or a Sewing day.
But I really enjoyed reading your Religion of Opinion, and I'll probably revisit it again sometime soon since I was a bit in a rush when I read it, and there's a lot of hefty content to think about.
Anyway, today I wrote an entire chapter for my Silmarillion fanfiction, Ill Chances and Strange Fates. (If you recall, I wrote a long post about it some weeks ago
here.) I took a break from the current arc and went all the way back to the beginning of the book, when
Maitimo and Aranya first met. This chapter was a hilarious one to write and I really enjoyed it! Maitimo is an awkward mess in general, being the equivalent of a teenager and struggling through growth spurts and voice cracks. He's also responsible for babysitting all his brothers and struggling to manage that and his studies. And Aranya basically looked at that pathetic mess and was like, "Yeah, I want that one." I'm not going to spoil the exact circumstances under which they met, because I do plan on posting the fic here and on AO3 sometime soon, and some of you might want to read it. But their initial conversation was really fun to write, being full of awkwardness and snarky banter. And even though I joke that Aranya decided Maitimo was a pathetic mess and she liked that, in all seriousness, she was amazed by how he politely and respectfully treated her as an equal, even though he's a direct heir to the throne and she's a servant.
Once I get the beginning arc wrapped up and connected to the later arc I started, I believe I will start posting it here and on AO3.
Even though my long-term goal is to finish my fantasy novel, this has been a very fun and refreshing project, and I think it's important for my brain to have another project to fall back on so I don't get burned out.
