The tricky part is trying to find balance with both. You can include promotion with your posts, like every time you make a new post, you can talk about it on your socials. But it might be worth it to slow down and spend some time with promotion? Also lots of social media sites nowadays have scheduling features. I’d definitely take advantage of them. You could spend a day or two on scheduling out the next couple weeks, then you can spend that off time working on your projects/posts.
If I can recommend it, I’d perhaps change your top banner? It’s a little unclear to have the gaming controller, which makes me think of gaming, rather than what you offer–fiction. I think having your book up there would be great
It may also be worthwhile seeing what other fiction writers on Patreon do, see if you can learn from their strategies
Best of luck ^^
