About this ebook
A revolutionary approach to enhancing productivity, creating flow, and vastly increasing your ability to capture, remember, and benefit from the unprecedented amount of information all around us.
For the first time in history, we have instantaneous access to the world’s knowledge. There has never been a better time to learn, to contribute, and to improve ourselves. Yet, rather than feeling empowered, we are often left feeling overwhelmed by this constant influx of information. The very knowledge that was supposed to set us free has instead led to the paralyzing stress of believing we’ll never know or remember enough.
Now, this eye-opening and accessible guide shows how you can easily create your own personal system for knowledge management, otherwise known as a Second Brain. As a trusted and organized digital repository of your most valued ideas, notes, and creative work synced across all your devices and platforms, a Second Brain gives you the confidence to tackle your most important projects and ambitious goals.
Discover the full potential of your ideas and translate what you know into more powerful, more meaningful improvements in your work and life by Building a Second Brain.
Tiago Forte
Tiago Forte has spent his career exploring a single question: how do we make the most of what we know? His answer became Building a Second Brain, a methodology now practiced by readers on every continent and inside organizations from Genentech to Toyota to the Inter-American Development Bank. That book, along with The PARA Method and Life in Perspective, has reached more than half a million readers in over twenty-five languages—and landed on the Wall Street Journal bestseller list. His ideas have surfaced in The New York Times, Harvard Business Review, Fast Company, Time, and elsewhere. But most of his thinking happens far from newsrooms—in Valle de Bravo, Mexico, a small town on a volcanic lake, where he lives with his wife and children. More at ForteLabs.com.

This book completely transformed the way I consume information. My biggest takeaway is to create digital notes and store them according to their ACTIONABILITY - directly into the folder containing a current project, instead of storing in subject folder/hierarchy where I tend to forget about them. I store them now in areas where I'm going to immediately use them. Highly recommend this book. - Rating: 3 out of 5 stars3/5

Some good ideas, overly stretched over 250 pages.

For anyone with lots to organise, or in need of lightening your mental load. This really helped clarify and simplify my system for saving information and organising my life digitally to support my goals, projects and just general day to day living. The biggest takeaway is to save and order information in terms of actionability, not from which source it came. You wouldn't put fresh, canned or frozen fruit in the same place simply because it's fruit, you'd put of where it is best going to be used.
The main points are all made by the end of chapter 7, but the numerous stories thereafter do hammer home the points with some added tips.1 person found this helpful

The problem with these "new and improved" knowledge management systems like this one is that they are over-complicated attempts to replicate the success Niklas Luhmann enjoyed with his Zettelkasten. Always go simple to remove friction and resistance. The "Second Brain" is not simple, it causes friction and therefore adds resistance.2 people found this helpful

The book is a practical guide to building a system for thinking, learning, and creating.
I found the explanations of CODE and PARA especially useful because they are simple, actionable, and backed by real examples. The author balances theory with practical techniques (like progressive summarisation, Hemingway bridge, and archipelago of ideas), making the book both inspiring and implementable.
For me, the biggest value lies in how it changes the mindset — from hoarding information to trusting a system, from focusing on final outputs to valuing intermediate work, and from scarcity to abundance. Author explained about scarce and abundance mindset but not told about how to overcome it.
Overall, it is not just about note-taking; it’s about designing a creative workflow that makes ideas compound over time. - Rating: 3 out of 5 stars3/5

El otro día hablaba con mi psiquiatra que yo necesito estar recordándome cuáles son mis metas, proyectos y prioridades, porque si no, muy fácilmente me desvío y termino no haciendo nada.
Este libro te da algunos parámetros para construir tu “segundo cerebro”, una herramienta digital para guardar, organizar, pensar y crear. Me gustó porque te da algunos tips de cómo hacer tu propio segundo cerebro. Y al final te dice que debes ir siguiendo tu instinto, lo que te gusta, lo que no, pero todo con el fin de que no olvides cosas importantes.
Como muchos libros de productividad o autoayuda, siento que es muy repetitivo y pudo haber contado lo mismo con muchísimas páginas menos. Eso hizo que me costara mucho terminarlo. Pero bueno, ya quedó. - Rating: 3 out of 5 stars3/5

I had high hopes for this one, but Building a Second Brain didn’t quite deliver for me. If you already work in a digital environment and have some kind of organizational system, most of the content will feel pretty basic. There are a few interesting tips here and there, but nothing truly game-changing. A decent intro for beginners, but not essential if you’re already in the habit of managing digital notes and knowledge. - Rating: 3 out of 5 stars3/5

There was too much happening here for me to get much out of it. The concept worked well enough for the author because it did feel like he distilled pertinent information from other books and created his own here, but it didn’t really work for me. Basically it boils down to taking notes better, but I’m not sure who exactly was the best audience here (business or personal development or creative life or…). - Rating: 5 out of 5 stars5/5

This book, in my opinion, is necessary for most people that will be working in knowledge work.
Files and information on a computer are such a critical part of today's work, that having a system to deal with the massive amount we accumulate is necessary. I learned multiple helpful mindsets and tools that I can use to produce a better product in what I deliver to others.

Building a Second Brain: A Proven Method to Organize Your Digital Life and Unlock Your Creative Potential, by Tiago Forte. Simon Acumen. New York | Amsterdam/Antwerp | London | Toronto | Sydney/Melbourne | New Delhi.To Lauren, my partner, my muse, and my greatest inspiration in everything I do
Introduction
The Promise of a Second Brain
How often have you tried to remember something important and felt it slip through your mental grasp?
Perhaps you were having a conversation and couldn’t remember a fact that would have convincingly supported your point of view. Maybe you conceived of a brilliant new idea while driving or in transit, but by the time you arrived at your destination, it had evaporated. How often have you struggled to recall even one useful takeaway from a book or article you read in the past?
As the amount of information we have access to grows, such experiences are becoming more and more common. We’re flooded with more advice than ever promising to make us smarter, healthier, and happier. We consume more books, podcasts, articles, and videos than we could possibly absorb. What do we really have to show for all the knowledge we’ve gained? How many of the great ideas we’ve had or encountered have faded from our minds before we even had a chance to put them into practice?
We spend countless hours reading, listening to, and watching other people’s opinions about what we should do, how we should think, and how we should live, but make comparatively little effort applying that knowledge and making it our own. So much of the time we are information hoarders,
stockpiling endless amounts of well-intentioned content that only ends up increasing our anxiety.
This book is dedicated to changing that. You see, all the content you consume online and through all the different kinds of media you have at your disposal isn’t useless. It’s incredibly important and valuable. The only problem is that you’re often consuming it at the wrong time.
What are the chances that the business book you’re reading is exactly what you need right at this moment? What are the odds that every single insight from a podcast interview is immediately actionable? How many of the emails sitting in your inbox actually require your full attention right now? More likely, some of it will be relevant now, but most of it will become relevant only at some point in the future.
To be able to make use of information we value, we need a way to package it up and send it through time to our future self. We need a way to cultivate a body of knowledge that is uniquely our own, so when the opportunity arises—whether changing jobs, giving a big presentation, launching a new product, or starting a business or a family—we will have access to the wisdom we need to make good decisions and take the most effective action. It all begins with the simple act of writing things down.
I’ll show you how this simple habit is the first step in a system I’ve developed called Building a Second Brain, which draws on recent advancements in the field of PKM—or personal knowledge management.I
In the same way that personal computers revolutionized our relationship with technology, personal finance changed how we manage our money, and personal productivity reshaped how we work, personal knowledge management helps us harness the full potential of what we know. While innovations in technology and a new generation of powerful apps have created new opportunities for our times, the lessons you will find within these pages are built on timeless and unchanging principles.
The Building a Second Brain system will teach you how to:
Find anything you’ve learned, touched, or thought about in the past within seconds.
Organize your knowledge and use it to move your projects and goals forward more consistently.
Save your best thinking so you don’t have to do it again.
Connect ideas and notice patterns across different areas of your life so you know how to live better.
Adopt a reliable system that helps you share your work more confidently and with more ease.
Turn work off
and relax, knowing you have a trusted system keeping track of all the details.
Spend less time looking for things, and more time doing the best, most creative work you are capable of.
When you transform your relationship to information, you will begin to see the technology in your life not just as a storage medium but as a tool for thinking. Like a bicycle for the mind,II
once we learn how to use it properly, technology can enhance our cognitive abilities and accelerate us toward our goals far faster than we could ever achieve on our own.
In this book I will teach you how to create a system of knowledge management, or a Second Brain.
III
Whether you call it a personal cloud,
field notes,
or an external brain
as some of my students have done, it is a digital archive of your most valuable memories, ideas, and knowledge to help you do your job, run your business, and manage your life without having to keep every detail in your head. Like a personal library in your pocket, a Second Brain enables you to recall everything you might want to remember so you can achieve anything you desire.
I’ve come to believe that personal knowledge management is one of the most fundamental challenges—as well as one of the most incredible opportunities—in the world today. Everyone is in desperate need of a system to manage the ever-increasing volume of information pouring into their brains. I’ve heard the plea from students and executives, entrepreneurs and managers, engineers and writers, and so many others seeking a more productive and empowered relationship with the information they consume.
Those who learn how to leverage technology and master the flow of information through their lives will be empowered to accomplish anything they set their minds to. At the same time, those who continue to rely on their fragile biological brains will become ever more overwhelmed by the explosive growth in the complexity of our lives.
I’ve spent years studying how prolific writers, artists, and thinkers of the past managed their creative process. I’ve spent countless hours researching how human beings can use technology to extend and enhance our natural cognitive abilities. I’ve personally experimented with every tool, trick, and technique available today for making sense of information. This book distills the very best insights I’ve discovered from teaching thousands of people around the world how to realize the potential of their ideas.
With a Second Brain at your fingertips, you will be able to unlock the full potential of your hidden strengths and creative instincts. You will have a system that supports you when you are forgetful and unleashes you when you are strong. You will be able to do and learn and create so much more, with so much less effort and stress, than was ever possible before.
In the next chapter, I’ll tell you the story of how I built my own Second Brain, and the lessons I learned along the way about how you can build one for yourself.

PART ONE
The Foundation
Understanding What’s Possible
Chapter 1
Where It All Started
Your mind is for having ideas, not holding them.
—David Allen, author of Getting Things Done
One spring day during my junior year of college, for no apparent reason, I began to feel a small pain in the back of my throat.
I thought it was the first sign of a flu coming on, but my doctor couldn’t find a trace of illness. It slowly got worse over the next few months, and I began to visit other, more specialized doctors. They all arrived at the same conclusion: there’s nothing wrong with you.
Yet my pain continued getting worse and worse, with no remedy in sight. Eventually it became so severe that I had trouble speaking or swallowing or laughing. I did every diagnostic test and scan imaginable, desperately looking for answers for why I was feeling this way.
As months and then years passed, I began to lose hope that I would ever find relief. I started taking a powerful anti-seizure medication that temporarily relieved the pain, but there were terrible side effects, including a numbing sensation throughout my body and severe short-term memory loss. Entire trips I took, books I read, and precious experiences with loved ones during this period were wiped from my memory as if they never happened. I was a twenty-four-year-old with the mind of an eighty-year-old.
As my ability to express myself continued to deteriorate, my discouragement turned to despair. Without the ability to speak freely, so much of what life had to offer—friendships, dating, traveling, and finding a career I was passionate about—seemed like it was slipping away from me. It felt like a dark curtain was being drawn over the stage of my life before I even had a chance to start my performance.
A Personal Turning Point—Discovering the Power of Writing Things Down
One day, sitting in yet another doctor’s office waiting for yet another visit, I had an epiphany. I realized in a flash that I was at a crossroads. I could either take responsibility for my own health and my own treatment from that day forward, or I would spend the rest of my life shuttling back and forth between doctors without ever finding resolution.
I took out my journal and began to write what I was feeling and thinking. I wrote out the history of my condition, through my own lens and in my own words, for the first time. I listed which treatments had helped and which hadn’t. I wrote down what I wanted and didn’t want, what I was willing to sacrifice and what I wasn’t, and what it would mean to me to escape the world of pain I felt trapped within.
As the story of my health began to take shape on the page, I knew what I needed to do. I stood up abruptly, walked over to the receptionist, and asked for my complete patient record. She looked at me quizzically, but after I answered a few questions, she turned to her files and began making photocopies.
My patient record amounted to hundreds of pages, and I knew I would never be able to keep track of them on paper. I started scanning every page on my family’s home computer, turning them into digital records that could be searched, rearranged, annotated, and shared. I became the project manager of my own condition, taking detailed notes on everything my doctors told me, trying out every suggestion they made, and generating questions to review during my next appointment.
With all this information in one place, patterns began to emerge. With my doctors’ help, I discovered a class of afflictions called functional voice disorders,
which included problems with any of the more than fifty pairs of muscles required to properly swallow a piece of food. I realized that the medications I was taking were masking my symptoms, and in the process making it harder to hear what they were telling me. What I had was not an illness or infection that could be eradicated with a pill—it was a functional condition that required changes in how I took care of my body.
I began to research how breathing, nutrition, vocal habits, and even past experiences in childhood can be manifested in the nervous system. I started to understand the mind-body connection and how my thoughts and feelings directly impacted the way my body felt. Taking notes on everything I learned, I devised an experiment: I would try a few simple lifestyle changes, such as improving my diet and regular meditation, combined with a series of voice exercises I learned from a voice therapist. To my shock and amazement, it began to work almost immediately. My pain didn’t disappear, but it became far more manageable.I
As I look back, my notes were as important in finding relief as any medicine or procedure. They gave me the chance to step back from the details of my condition and see my situation from a different perspective. For both the outer world of medicine and the inner world of sensations, my notes were a practical medium for turning any new information I encountered into solutions I could use.
From then on, I became obsessed with the potential of technology to channel the information all around me. I began to realize that the simple act of taking notes on a computer was the tip of an iceberg. Because once made digital, notes were no longer limited to short, handwritten scribbles—they could take any form, including images, links, and files of any shape and size. In the digital realm, information could be molded and shaped and directed to any purpose, like a magical, primordial force of nature.
I started using digital notetaking in other parts of my life. In my college classes, I turned stacks of disheveled spiral-bound notebooks into an elegant, searchable collection of lessons. I learned to master the process of writing down only the most important points from my classes, reviewing them on demand, and using them to compose an essay or pass a test. I had always been a mediocre student with average grades. My early schoolteachers would regularly send me home with report cards noting my short attention span and wandering mind. You can imagine my delight when I graduated from college with a nearly straight-A grade point average and university honors.
I had the misfortune of graduating into one of the worst job markets in a generation, in the aftermath of the 2008 financial crisis. Faced with few employment opportunities in the United States, I decided to join the Peace Corps, an overseas volunteer program that sends Americans to serve in developing countries. I was accepted and assigned to a small school in the eastern Ukrainian countryside, where I would spend two years teaching English to students aged eight to eighteen.
Working as a teacher with few resources and little support, my notetaking system once again became my lifeline. I saved examples of lessons and exercises anywhere I found them: from textbooks, websites, and USB drives passed around by other teachers. I mixed and matched English phrases, expressions, and slang into word games to keep my energetic third graders engaged. I taught the older students the basics of personal productivity—how to keep a schedule, how to take notes in class, and how to set goals and plan their education. I will never forget their appreciation as they grew up and used those skills to apply to universities and succeed in their first jobs. Years later, I still regularly receive messages of gratitude as the productivity skills I taught my former students continue to bear fruit in their lives.
I returned to the US after two years of service and was thrilled to land a job as an analyst at a small consulting firm in San Francisco. As excited as I was to start my career, I was also faced with a major challenge: the pace of work was frantic and overwhelming. Moving straight from rural Ukraine to the epicenter of Silicon Valley, I was utterly unprepared for the constant barrage of inputs that is a normal part of modern workplaces. Every day I received hundreds of emails, every hour dozens of messages, and the pings and dings from every device merged into a ceaseless melody of interruption. I remember looking around at my colleagues and wondering, How can anyone get anything done here? What’s their secret?
I knew only one trick, and it started with writing things down.
I started taking notes on everything I was learning using a notetaking app on my computer. I took notes during meetings, on phone calls, and while doing research online. I wrote down facts gleaned from research papers that could be used in the slides we presented to clients. I wrote down tidbits of insight I came across on social media, to share on our own social channels. I wrote down feedback from my more experienced colleagues so I could make sure I digested it and took it to heart. Every time we started a new project, I created a dedicated place on my computer for the information related to it, where I could sort through it all and decide on a plan of action.
As the information tide receded, I started to gain a sense of confidence in my ability to find exactly what I needed when I needed it. I became the go-to person in the office for finding that one file, or unearthing that one fact, or remembering exactly what the client had said three weeks earlier. You know the feeling of satisfaction when you are the only one in the room who remembers an important detail? That feeling became the prize in my personal pursuit to capitalize on the value of what I knew.
Another Shift—Discovering the Power of Sharing
My collection of notes and files had always been for my own personal use, but as I worked on consulting projects for some of the most important organizations in the world, I started to realize that it could be a business asset as well.
I learned from one of the reports we published that the value of physical capital in the US—land, machinery, and buildings for example—is about $10 trillion, but that value is dwarfed by the total value of human capital, which is estimated to be five to ten times larger. Human capital includes the knowledge and the knowhow embodied in humans—their education, their experience, their wisdom, their skills, their relationships, their common sense, their intuition.

If that was true, was it possible that my personal collection of notes was a knowledge asset that could grow and compound over time? I began to see my as-yet-unnamed Second Brain not just as a notetaking tool but as a loyal confidant and thought partner. When I was forgetful, it always remembered. When I lost my way, it reminded me where we were going. When I felt stuck and at a loss for ideas, it suggested possibilities and pathways.
At one point some of my colleagues asked me to teach them my organizing methods. I found that virtually all of them already used various productivity tools, such as paper notepads or the apps on their smartphones, but that very few did so in a systematic, intentional way. They tended to move information around from place to place haphazardly, reacting to the demands of the moment, never quite trusting that they’d be able to find it again. Every new productivity app promised a breakthrough, but usually ended up becoming yet another thing to manage.
Casual lunchtime chats with my colleagues turned into a book club, which became a workshop, which eventually evolved into a paid class open to the public. As I taught what I knew to more and more people and saw the immediate difference it made in their work and lives, it began to dawn on me that I had discovered something very special. My experience managing my chronic condition had taught me a way of getting organized that was ideal for solving problems and producing results now, not in some far-off future. Applying that approach to other areas of my life, I had found a way to organize information holistically—for a variety of purposes, for any project or goal—instead of only for one-off tasks. And more than that, I discovered that once I had that information at hand, I could easily and generously share it in all kinds of ways to serve the people around me.
The Origins of the Second Brain System
I began to call the system I had developed my Second Brain and started a blog to share my ideas about how it worked. These ideas resonated with a much wider audience than I ever expected, and my work was eventually featured in publications such as the Harvard Business Review, The Atlantic, Fast Company, and Inc., among others. An article I wrote about how to use digital notetaking to enhance creativity went viral in the productivity community, and I was invited to speak and teach workshops at influential companies like Genentech, Toyota, and the Inter-American Development Bank. In early 2017, I decided to create an online course called Building a Second Brain
to teach my system on a wider scale.II
In the years since, that program has produced thousands of graduates from more than one hundred countries and every walk of life, creating an engaged and inquisitive community where the lessons in this book have been honed and refined.
In the next couple of chapters, I’ll show you how the practice of creating a Second Brain is part of a long legacy of
