[Book 29] Building a Second Brain by Tiago Forte

Building a Second Brain explains an effective way to capture, organize, distill and express information for future use. Given the limitations of our memory, building a “second brain” involves creating a personalized digital archive of what resonates with each of us. Tiago emphasizes that the benefits also extend beyond mere archiving. Writing is an effective way to enhance our thinking, and thus having easily accessible and organized prior learnings and experiences can catalyze how we transform ideas into creative output. This book has taught me how to enhance my thinking, creativity, and curiosity through the structure and connectivity of my notes. Adopting elements of this approach helped lay the foundation for creating this blog and book summaries.

You should read this book if you…

• want a better way to organize and distill information
• seem to forget most of what you learned after a few months
• seek an effective method to connect ideas

“When the opportunity arrives to do our best work, it’s not the time to start reading books and doing research. You need that research to already be done. You can prepare in advance for the future challenges and opportunities you don’t even yet know you’ll face, by taking advantage of the effort you’re already spending reading books, learning new things, and simply being curious about the world around you“

Key Highlights

1. 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
2. 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
3. As this way of working with information continues over days and weeks and months, the way your mind works begins to change. You start to see recurring patterns in your thinking: why you do things, what you really want, and what’s really important to you. Your Second Brain becomes like a mirror, teaching you about yourself and reflecting back to you the ideas worth keeping and acting on. Your mind starts to become intertwined with this system, leaning on it to remember more than you ever could on your own
4. This tendency is known as recency bias. We tend to favor the ideas, solutions, and influences that occurred to us most recently, regardless of whether they are the best ones. Now imagine if you were able to unshackle yourself from the limits of the present moment, and draw on weeks, months, or even years of accumulated imagination
5. The CODE Method: The Four Steps to Remembering What Matters To guide you in the process of creating your own Second Brain, I’ve developed a simple, intuitive four-part method called “CODE”—Capture; Organize; Distill; Express
6. The best way to organize your notes is to organize for action, according to the active projects you are working on right now. Consider new information in terms of its utility, asking, “How is this going to help me move forward one of my current projects?”
7. Every time you take a note, ask yourself, “How can I make this as useful as possible for my future self?” That question will lead you to annotate the words and phrases that explain why you saved a note, what you were thinking, and what exactly caught your attention. Your notes will be useless if you can’t decipher them in the future, or if they’re so long that you don’t even try. Think of yourself not just as a taker of notes, but as a giver of notes—you are giving your future self the gift of knowledge that is easy to find and understand
8. If you’re not surprised, then you already knew it at some level, so why take note of it? Surprise is an excellent barometer for information that doesn’t fit neatly into our existing understanding, which means it has the potential to change how we think
9. “emotions organize—rather than disrupt—rational thinking.” When something resonates with us, it is our emotion-based, intuitive mind telling us it is interesting before our logical mind can explain why
10. Known as the “Generation Effect,” researchers have found that when people actively generate a series of words, such as by speaking or writing, more parts of their brain are activated when compared to simply reading the same words. Writing things down is a way of “rehearsing” those ideas, like practicing a dance routine or shooting hoops, which makes them far more likely to stick
11. The moment you first encounter an idea is the worst time to decide what it means. You need to set it aside and gain some objectivity. With a Second Brain as a shield against the media storm, we no longer have to react to each idea immediately, or risk losing it forever
12. Capture isn’t about doing more. It’s about taking notes on the experiences you’re already having. It’s about squeezing more juice out of the fruit of life, savoring every moment to the fullest by paying closer attention to the details
13. With the PARA system, every piece of information you want to save can be placed into one of just four categories: Projects: Short-term efforts in your work or life that you’re working on now. Areas: Long-term responsibilities you want to manage over time. Resources: Topics or interests that may be useful in the future. Archives: Inactive items from the other three categories
14. This is why it’s so important to separate capture and organize into two distinct steps: “keeping what resonates” in the moment is a separate decision from deciding to save something for the long term
15. When the opportunity arrives to do our best work, it’s not the time to start reading books and doing research. You need that research to already be done. You can prepare in advance for the future challenges and opportunities you don’t even yet know you’ll face, by taking advantage of the effort you’re already spending reading books, learning new things, and simply being curious about the world around you
16. The first two steps of CODE, Capture and Organize, make up divergence. They are about gathering seeds of imagination carried on the wind and storing them in a secure place. This is where you research, explore, and add ideas. The final two steps, Distill and Express, are about convergence. They help us shut the door to new ideas and begin constructing something new out of the knowledge building blocks we’ve assembled
17. Instead of trying to optimize your mind so that it can manage every tiny detail of your life, it’s time to fire your biological brain from that job and give it a new one: as the CEO of your life, orchestrating and managing the process of turning information into results. We’re asking your biological brain to hand over the job of remembering to an external system, and by doing so, freeing it to absorb and integrate new knowledge in more creative ways
