I have changed genres lol. I went from sci-fi romance, to paranormal romance, and am now writing contemporary MC romance. I also write traditional MF, poly MFM, MMF, MMM, and MM romance.
I used to scour them relentlessly and I would get upset if anyone didn't like my book. Rejections hurt big time. But I had an author remind me that reviews are for other readers, so I stopped reading them and only listen to my beta readers and editors. Although I do appreciate it when readers contact me if they find grammatical issues.
Oh well, not having experience in their body. I have to imagine what they are feeling. I used to ask my husband, "Okay, so hypothetically if this happened, how would you react?".
I learned a lot from my editor! I can't even make a list that long. And I still make lots of mistakes, for example, repeated words. I'm a pro at using certain words too much and too close together.
