Ohh I understand why you want to niche down but I am concerned you could get bored or run out of ideas. I’d recommend a 70/30 type of thing where 70 percent is about what you mainly want to write about (like how I do with tarot and some people-pleasing and mental health stuff in there) and then 30 percent of other (like my quirky and fascinating facts pub and anything else I want to talk about like my weight loss I talk about sometimes). Just something to think about! You gotta do what feels best for you!
