I'm currently writing a novella. I also have plans for a non-fiction work.
I'm also publishing free content at https://taylor.town
> I don't think it's worth it to publish free content anymore
If "worth it" means "make you rich", I wouldn't recommend pursuing writing :)
If "worth it" means "provides meaning to yourself and others", books and blogs will continue to be enriching!
