The book doesn’t have to be directly about your work but should have generated new ideas, understanding and/or excitement on the topic for you. One book only.

My “changed my life” book is a classic textbook — "Marketing Management" by Philip Kotler. The text is traditional in its overview approach to the topic and its dense layout — pretty much like the textbooks you’ve known. But it opened up a new world for me, and I live in that world now. NOTE: I’m pointing you to the inexpensive 12th edition, two editions ago, because that will serve your purposes. Turn to this guide for core principles, not updates on innovations and new tools best sourced online.
