Business lessons from books

Hello everyone! I really enjoy reading books and would love to know some of your recommendations! What are the books that taught you something you are using in your business? Mine would be: $100M Offers - Alex Hormozi - how to make the offers, for me one of the best books about sales No Rules Rules - Reed Hastings, Erin Meyer - book about company culture and HR - "If a member of your team would tell you they leave, would you be relieved or would you try hard to make them stay?" The Lean Startup - Eric Ries - make a hypothesis and test it - stay lean as long as you can, do not try to behave like a corporate, full of processes unless it is really needed
