Branding and Reader Magnet Question

I recently listened to the opening of an interview with Russell Nohelty. He made a claim that I already agree with. I actually teach my drama students the idea at the beginning of the year and remind them at the beginning of every class:

“We have to get over ourselves. Getting over self-doubt is crucial for building a world-class Substack.”

I would say it’s also crucial for getting on any stage: in a theatre, in a publication, on a platform, etc.

So, I believe this is TRUE.

HOWEVER…

How does this intersect with BRAND BUILDING? Specifically, what if part of my writing is very serious and part of it is cheeky and fun?

Do I put it all out there, risking losing one or the other reader? How carefully do I control my brand/content reputation? E

ven more specifically, I usually write very sincere faith-based fiction, but I have a cheeky idea for a non-fiction reader magnet that I think a lot of my Timothy will like. Do I send that Reader Magnet out into the world and risk offending my more serious readers?

Now I’ll get even more specific: at the Novel Marketing Conference my table talked about how writing for a Timothy that is a child means also marketing for a parent or adult in that child’s life? I think the kids will like my cheeky reader magnet. Some of their parents might not.

What are your thoughts?
