Yes, I may share this in a future post, but all writing (a message to your mum or a 900-page novel) should be clear in its CAP.

C = Context (what type of writing) A = Audience (who is reading) P = Purpose (why you are publishing)

For sure, writing falls flat if it does not resonate with the reader. Still, for creative work or life writing, I like to start from the perspective of ME being the audience.
