Not sure any book i've read has changed my life. Many have influenced the way I think about certain aspects of my life. For example, Poor Charlie's Almanack helped me become more disciplined. This book has a lot of wisdom, quotes from well-known historical figures, and many proverbs to make you go.."wow, I've never thought about it like that."
Influence-The Psychology of Persuasion and Factfulness both explain, quite well i think, common logical fallacies, misconceptions, and implicit biases we all share. Being mindful of such pre-programmed deceptions, I was able to begin to exercise ways in which to recognize when others are attempting to deceive me by exploiting my programming.
Brave New World, Amusing Ourselves to Death, Medium is the Message, Understanding the Media, Fahrenheit 451, 1984, were some of the books I read that change the way I think about human beings within a society: how technology influences our perception of reality; technology is never one sided, it gives something but also takes something away (internet/connection and lack of individual privacy), etc.
Of course, Bogleheads Guide to Investing, Little Book of Common-Sense Investing, The Bond Book, The Intelligent Investor, Money Mustache Blog, Bogleheads forum, Investopedia, are some of the more frequent sources of my financial knowledge acquisition.
