This list contains the books I believe everyone who wants to truly understand what digital design is all about needs to read. I've tried to roughly categorize them into more foundational topics and then somewhat along the double diamond: finding the right problem and finding the right solution. To provide a glimpse into the future, I also list some books on designing for an with (a selection of) novel types of interfaces.
In this article I want to recommend five books that I believe are essentials in trying times like these: Rosling et al.'s Factfulness; Marcus Aurelius' Meditations; Epictetus' Enchiridion; Seneca's On the Shortness of Life; and Dobelli's The Art of Thinking Clearly.
All the books I read in 2018: Excellent Sheep 💎; The Design of Everyday Things 💎; The Little Book of Hygge; Spelunky; The Subtle Art of Not Giving a F*ck; Che Guevara; How to become a UX leader; Joy, Inc.; Requiem; QualityLand; & The Road To Prosperity 💎.
