Non-Fiction: "How to Win Friends and Influence People" by Dale Carnegie, because it changed my understanding of people for the better. "Surely You're Joking, Mr. Feynman!" by Richard Feynman, because it gave me a model for how to enjoy life. "Models" by Mark Manson, because it helped shape my understanding of heterosexual relationships. "An Introduction to General Systems Thinking" by Gerald Weinberg, because it illuminates the general laws underlying all systems. Fiction: "Stranger in a Strange Land" by Robert A Heinlein, because it showed me a philosophy and "spirituality", for lack of a better word, that I could agree with. "The Fountainhead" and "Atlas Shrugged" by Ayn Rand, because they showed me how human systems break, and they provided human models for how to see and live in, through, and past those broken systems. "Harry Potter and the Methods of Rationality" by Eliezer Yudkowsky, because it set the bar (high) for all future fiction, especially when it comes to the insightful portrayal of the struggle between good and evil.
