1 simple writing tip:
Write letters to your younger self.
What are 5-10 lessons you wish a younger you knew?
As a spouse?
As a worker?
As a parent?
As a friend?
As a person, in general?
Tell us those lessons.
Use stories to specify those lessons.
Don’t worry about a niche.
Just write stuff you wish younger you could’ve read.
And you'll be well on your way to growing a following.
