"I read a blog post or a book on how to charge more."
This is not to say that a post like this doesn't have any value - or a book like Brennan Dunn's book. But sometimes, when I read stuff like that, I wonder how much is actually survivorship bias and how much one can REALLY learn from a post like this.
It's a bit like Amazon reviews of books: Half of them are for people who have read the book and start to discuss things retrospectively.
