Factfulness: Ten Reasons We're Wrong About the World—and Why Things Are Better Than You Think

Demian by Hermann Hesse. I wanted to scream "Stop overthinking!" to the protagonist. Something I can relate to. Siddharta by Hermann Hesse. Helped me understand that a perfect life is a collection of ups and downs and that one must accept it all. Amerika by Franz Kafka. Could relate to the protagonist because people take advantage of his naivety. Factfulness by Hans Rosling. Made me see the world in a less pessimistic way.

Factfulness: Ten Reasons We're Wrong About the World--and Why Things Are Better Than You Think - Hans Rosling

Factfulness and Enlightenment Now utterly transformed my outlook on life and the state of the world. These two books turned me from a cynical complainer into an optimist. Cannot recommend them highly enough.
