1. Be vulnerable and share your mistakes. Avoid a triumphalist “everything works” PoV
2. Write about your actual lived personal experiences.
3. Try to have a sense of humor
4. Have an informed opinion or PoV - strong opinions held weakly.
5. Be casual. Don’t treat a blog like it’s a research paper.
I won't claim to be a professional author or even good, but lately I've been trying to get more into the "it's a person who writes actually" direction and this was an exploration into that, so any sort of feedback would be most welcome, if you have the time!
