Part 1 is about the purpose and importance of having principles in general, having nothing to do with mine. Part 2 explains my most fundamental life principles that apply to everything I do. Part 3, explains my management principles as they are being lived out at Bridgewater. Since my management principles are simply my most fundamental life principles applied to management, reading Part 2 will help you to better understand Part 3, but it’s not required—you can go directly to Part 3 to see what my management principles are and how Bridgewater has been run. One day I’d like to write a Part 4 on my investment principles. If you are looking to get the most bang for your buck (i.e., understanding for the effort), I suggest that you read Parts 1 and 2, and the beginning of Part 3 (through the Summary and Table of Principles) which will give you nearly the whole picture. It’s only about 55 pages of a normal size book. Above all else, I want you to think for yourself—to decide 1) what you want, 2) what is true and 3) what to do about it. I want you to do that in a clear-headed thoughtful way, so that you get what you want. I wrote this book to help you do that. I am going to ask only two things of you—1) that you be open-minded and 2) that you honestly answer some questions about what you want, what is true and what you want to do about it. If you do these things, I believe that you will get a lot out of this book. If you can’t do these things, you should reflect on why that is, because you probably have discovered one of your greatest impediments to getting what you want out of life.

     You have about 80,000 hours in your career: 40 hours a week, 50 weeks a year, for 40 years. This means your choice of career is one of the most important decisions you’ll ever make. Make the right choices, and you can help solve some of the world’s most pressing problems, as well as have a more rewarding, interesting life. For such an important decision, however, there’s surprisingly little good advice out there. Most career advice focuses on things like how to write a CV, and much of the rest is just (misleading) platitudes like “follow your passion”. Most people we speak to don’t even use career advice – they just speak to friends and try to figure it out for themselves. When it comes to helping others with your career, the advice usually assumes you need to work as a teacher, doctor, charity worker, and so on, even though these paths might not be a good fit for you, and were not what the highest-impact people in history did. This guide is based on five years of research conducted alongside academics at the University of Oxford. It aims to help you find a career you enjoy, you’re good at, and that tackles the world’s most pressing problems. It covers topics like: 1. What makes for a dream job, and why “follow your passion” can be misleading. 2. Why the most effective ways to make a difference aren’t always the obvious ones like working at a charity, or becoming a doctor. 3. How to compare global problems, like climate change and education, in terms of their scale and urgency. 4. How to discover and develop your strengths. It’s also full of practical tips and tools. At the end, you'll have a plan to use your career in a way that's fulfilling and does good.

    Real rationality, of the sort studied by psychologists, social scientists, and mathematicians. The kind of rationality where you make good decisions, even when it's hard; where you reason well, even in the face of massive uncertainty; where you recognize and make full use of your fuzzy intuitions and emotions, rather than trying to discard them. In "Rationality: From AI to Zombies," Eliezer Yudkowsky explains the science underlying human irrationality with a mix of fables, argumentative essays, and personal vignettes. These eye-opening accounts of how the mind works (and how, all too often, it doesn't!) are then put to the test through some genuinely difficult puzzles: computer scientists' debates about the future of artificial intelligence (AI), physicists' debates about the relationship between the quantum and classical worlds, philosophers' debates about the metaphysics of zombies and the nature of morality, and many more. In the process, "Rationality: From AI to Zombies" delves into the human significance of correct reasoning more deeply than you'll find in any conventional textbook on cognitive science or philosophy of mind. A decision theorist and researcher at the Machine Intelligence Research Institute, Yudkowsky published earlier drafts of his writings to the websites Overcoming Bias and Less Wrong. "Rationality: From AI to Zombies" compiles six volumes of Yudkowsky's essays into a single electronic tome. Collectively, these sequences of linked essays serve as a rich and lively introduction to the science—and the art—of human rationality.

    If the facts don't hang together on a latticework of theory, you don't have them in a usable form. You've got to have models in your head."- Charlie Munger, investor, vice chairman of Berkshire HathawayThe world's greatest problem-solvers, forecasters, and decision-makers all rely on a set of frameworks and shortcuts that help them cut through complexity and separate good ideas from bad ones. They're called mental models, and you can find them in dense textbooks on psychology, physics, economics, and more.Or, you can just read Super Thinking, a fun, illustrated guide to every mental model you could possibly need. How can mental models help you? Well, here are just a few examples... • If you've ever been overwhelmed by a to-do list that's grown too long, maybe you need the Eisenhower Decision Matrix to help you prioritize. • Use the 5 Whys model to better understand people's motivations or get to the root cause of a problem. • Before concluding that your colleague who messes up your projects is out to sabotage you, consider Hanlon's Razor for an alternative explanation. • Ever sat through a bad movie just because you paid a lot for the ticket? You might be falling prey to Sunk Cost Fallacy. • Set up Forcing Functions, like standing meeting or deadlines, to help grease the wheels for changes you want to occur.So, the next time you find yourself faced with a difficult decision or just trying to understand a complex situation, let Super Thinking upgrade your brain with mental models.Note: in the US the subtitle is The Big Book of Mental Models and outside it is Upgrade Your Reasoning and Make Better Decisions with Mental Models.

     From the author:   “For the last two years, I’ve interviewed more than 200 world-class performers for my podcast, The Tim Ferriss Show. The guests range from super celebs (Jamie Foxx, Arnold Schwarzenegger, etc.) and athletes (icons of powerlifting, gymnastics, surfing, etc.) to legendary Special Operations commanders and black-market biochemists. For most of my guests, it’s the first time they’ve agreed to a two-to-three-hour interview. This unusual depth has helped make The Tim Ferriss Show the first business/interview podcast to pass 100 million downloads.   “This book contains the distilled tools, tactics, and ‘inside baseball’ you won’t find anywhere else. It also includes new tips from past guests, and life lessons from new ‘guests’ you haven’t met.   “What makes the show different is a relentless focus on actionable details. This is reflected in the questions. For example: What do these people do in the first sixty minutes of each morning? What do their workout routines look like, and why? What books have they gifted most to other people? What are the biggest wastes of time for novices in their field? What supplements do they take on a daily basis?   “I don’t view myself as an interviewer. I view myself as an experimenter. If I can’t test something and replicate results in the messy reality of everyday life, I’m not interested.   “Everything within these pages has been vetted, explored, and applied to my own life in some fashion. I’ve used dozens of the tactics and philosophies in high-stakes negotiations, high-risk environments, or large business dealings. The lessons have made me millions of dollars and saved me years of wasted effort and frustration.   “I created this book, my ultimate notebook of high-leverage tools, for myself. It’s changed my life, and I hope the same for you.”

    In other words, we have what Julia Galef calls a soldier mindset. From tribalism and wishful thinking, to rationalizing in our personal lives and everything in between, we are driven to defend the ideas we most want to believe--and shoot down those we don't.But if we want to get things right more often, argues Galef, we should train ourselves to have a scout mindset. Unlike the soldier, a scout's goal isn't to defend one side over the other. It's to go out, survey the territory, and come back with as accurate a map as possible. Regardless of what they hope to be the case, above all, the scout wants to know what's actually true.In The Scout Mindset, Galef shows that what makes scouts better at getting things right isn't that they're smarter or more knowledgeable than everyone else. It's a handful of emotional skills, habits, and ways of looking at the world--which anyone can learn. With fascinating examples ranging from how to survive being stranded in the middle of the ocean, to how Jeff Bezos avoids overconfidence, to how superforecasters outperform CIA operatives, to Reddit threads and modern partisan politics, Galef explores why our brains deceive us and what we can do to change the way we think.

    We donate our time and money to charities and causes we deem worthy, choose careers we consider meaningful, and patronize businesses and buy products we believe make the world a better place. Unfortunately, we often base these decisions on assumptions and emotions rather than facts. As a result, even our best intentions often lead to ineffective—and sometimes downright harmful—outcomes. How can we do better? While a researcher at Oxford, trying to figure out which career would allow him to have the greatest impact, William MacAskill confronted this problem head on. He discovered that much of the potential for change was being squandered by lack of information, bad data, and our own prejudice. As an antidote, he and his colleagues developed effective altruism, a practical, data-driven approach that allows each of us to make a tremendous difference regardless of our resources. Effective altruists believe that it’s not enough to simply do good; we must do good better. At the core of this philosophy are five key questions that help guide our altruistic decisions: How many people benefit, and by how much? Is this the most effective thing I can do? Is this area neglected? What would have happened otherwise? What are the chances of success, and how good would success be? By applying these questions to real-life scenarios, MacAskill shows how many of our assumptions about doing good are misguided. For instance, he argues one can potentially save more lives by becoming a plastic surgeon rather than a heart surgeon; measuring overhead costs is an inaccurate gauge of a charity’s effectiveness; and, it generally doesn’t make sense for individuals to donate to disaster relief. MacAskill urges us to think differently, set aside biases, and use evidence and careful reasoning rather than act on impulse. When we do this—when we apply the head and the heart to each of our altruistic endeavors—we find that each of us has the power to do an astonishing amount of good.
