Start with your reader's situation, not your ideas
Before writing a single word, ask: what does my reader need this week, what problem are they sitting with, what question keeps coming up in their work or life?
The best newsletter issues feel like they arrived at exactly the right moment — because the writer thought about the reader before thinking about themselves. That sense of perfect timing is not an accident. It is the result of a deliberate shift in orientation: away from "what do I want to share" and toward "what does my reader need right now."
This one habit separates newsletters people look forward to from newsletters people eventually unsubscribe from.
