Hey this is a good topic and I’m learning how to write on medium through a teacher who says niching down is important but only to a degree because as you said you don’t want to bore anyone. I’d say 60 to 70 percent of the time I write about tarot and metaphysics as I have a pub for that. The remainder of the time I write about facts and tips, mental health, and once in a while other miscellaneous thing. It’s because I can write about those things but there is no way 100% of my writing would be about tarot. I want to appeal to those who I can help with practical stuff too.
