The post is already flagged, but the general point here is: then directly challenge what’s wrong.
And it’s helpful if you look at this through the lens of “Things I’ve learned”, emphasis on the author’s journey. To claim that what others have learned about how they live their own lives is downright wrong…strikes me as a rather limited way of thinking about the spectrum of situations we all find ourselves in.
If the author was claiming that all readers should alter their lives according to his own discoveries, I’d have more issues with it.
