Genre does make a difference, but none are easier than others, and all have their own bunch of dedicated readers and expectations. I write in romance (which is one of the ones people always think is easier!) but the readers are harsh and the competition is fierce, so it brings its own set of challenges. The positives are the readers do a lot of your marketing for you if they love your books, and they're generally a really engaged audience re. Social Media.
I think you said you write womens fic? I can't speak much about that from an indy front but if you can find similar authors who publish indy, and find where they hang out, then that's a really good step. Join their reader groups on FB, study what they're doing. I met a few WF authors at 20books conference so they definitely exist!
I did that when I first started and have had some amazing opportunities that way (newsletter swaps, participation in anthologies, help with things I didn't understand etc).
My first two were a duet, second two were a duet, fifth book standalone and sixth book standalone. I chop and change depending on how long I think it will be, I'm not a plotter at all -- I write completely into the dark so there was nothing intentional about that, there are positives and negatives to series/ standalone. The duets were good because both book 1s ended up being popular, so I had a decent income from book 2s but I can imagine it would be really discouraging if book 1 flopped, having to continue with it because you've left a cliffhanger for the few people who did read the book.
But the good thing with indy is you learn from your mistakes, and you implement them on the next book. Duet didn't work? Write a standalone!
Book 1 was a hot mess so I got Pro Writing Aid for Book 2. I then learned being a grammar nazi was killing my character voice in Book 2, so for Book 3 I scaled right back on the grammar and just fixed spelling. Huge success. Book 4 I didn't give a good enough ending, so for Book 5 I went to town on the ending and gave them a 4k epilogue.
You get the idea. You can't learn all the lessons before you've hit publish, it's definitely a journey and as long as your willing to keep pushing forwards, tweaking things, learning, adjusting, and not take yourself to seriously then I do believe anyone can do it
