As the maoral-less L. Ron Hubbard would say...
"You don't make money selling a book, if you want to be rich, start a religion"

Peterson is just running a dumb cult of generic (kinda bad for most people) advice that hinges on the shared identity of sad lonely boys.

Peter Pan in the books is sad as shit, advice to never grow up and never try to be better just makes people more lonely and miserable.
