I can't really tell what this book was about.
David Brooks describes the lives of two fictional individuals, who end up getting married. While it's not really their existence that is interesting, it is the generalizations coming from decades of research that make the book so insightful

Most of what is written in this book feels like common knowledge. I have been privileged to have read and discussed many of the studies mention in my classes, so it was repetition. Good though.

It was cool. Nice. Life is interesting. Human beings are too. So fascinating!
