"Managing Humans" by Michael Lopp made a huge impression on me and my career. https://www.amazon.com/Managing-Humans-Humorous-Software-Eng...

Also, "The Phoenix Project" which IMO is a groundbreaking work on how to make IT/business more effective (and the start of the DevOps movement). https://www.amazon.com/Phoenix-Project-DevOps-Helping-Busine...

Even if you're not a manager, both books are very approachable and packed with great lessons about how improve and better work with people, teams, and business.
