Well, please don't read me in that case. I know absolutely nothing about writing technqiue. I never went to school to learn it and I have never been taught it.
I was first published when I was 10 years old, have seldom had rejections. So I have, essentially, been in print for 60 years.
What I say here is based on my observation and analysis. The exception is SEO because that is what gets my work to the top of Google.
I also don't read all the great literary writers because they bore the hell out of me. So I'm a total lost cause. :)
By the way, English is not my first language, but my mother sent myself and my siblings to English schools so that we could become fluent in it. I don't find any fun in learning language, and right now I have to learn Portuguese. Fortunately, because I have 5 years Latin, it won't be so difficult because I recognise a lot of the words.
There are other people on Medium that know more about the stuff you are interested in.
Best of luck.
