The Promise of Second Brain
The second brain is Personal Knowledge Management (PKM). It is a tool to connect ideas, write and store important notes from various knowledge formats, such as books, podcasts, videos, etc.
It is a system for organizing, taking, and connecting our knowledge.
The Superpowers of a Second Brain
-
Making our ideas concrete: concrete. every idea is initially too vague to understand and only juggling around in our heads. If we don’t write it down somewhere — with all of today’s distractions, the chance is we’ll forget about it in the next moment. We are also a visual human; we tend to like a sense of physical stuff. Something that we can see, adjust, and organize. So, to make our ideas concrete, we need to immediately write them down and, in a way, manage and visualize them.
-
Revealing new associations between ideas: reveal. Creativity is about connecting ideas, especially ideas that don’t seem to be connected. Highly creative people based on neuroscientist Nancy C. Andreason’s version is “Creative people are better at recognizing relationships, making associations and connections.”
By keeping diverse kinds of material in one place, we facilitate this connectivity and increase the likelihood that we’ll notice an unusual association.
-
Incubating our ideas over time: Incubate. We tend to favor ideas, solutions and influences that occurred to us most recently, regardless of whether they are the best ones. Imagine if we can use weeks, months, or even years of accumulated imagination or ideas.
Having a second brain where lots of ideas can be permanently saved for the long term turns the passage of time into your friend.
-
Sharpening our unique perspectives: Sharpen. Those three processes are about capturing and organizing ideas. The real benefit is after those processes, when we can use the second brain as a tool to sharpen our unique perspective about everything we want to do. Imagine a soldier going to war with full ammo.
Remembering, Connecting, Creating: The Three Stages of Personal Knowledge Management
Everyone has their way of remembering, connecting, and create something. But people who leverage the secodn brain will do that with superpowers. It is a never-ending process; we will need to adjust and adapt how we use our note so that they remain relevant and useful.
The CODE Method: The Four Steps to Remembering What Matters
- Capture: Keep What Resonates
- The key principle here is capture only the ideas and insights that truly resonate with us and we think are noteworthy. I don’t know how to stress this enough, but, keep only what resonates in a trusted place that you control, and leave the rest aside.
- When something resonates, it walks on intuitive level. Don’t worry about why it resonates, just look inside for a feeling of pleasure, curiosity, wonder, or excitement. Often, the ideas that resonate are the ones that are most unusual, counterintuitive, interesting, or potentially useful.
- Organize: Save for Actionability
- Once you have begun capturing notes with the ideas that resonate with you, you’ll eventualy feel the need to organize them.
- The best way to organize your notes is to organize for action. Consider new information in terms of its utility, asking, “How is this going to help me move forward one of my current projects?”
- Distill: Find the Essence
- Once you start capturing ideas in a central place and organizing them for action, you’ll inevitably begin to notice patterns and connections between them.
- Human mind is like hot frying pan of associations — throw a handful of seeds in there and they’ll explode into new ideas like popcorn.
- There is a powerful way to facilitate and speed up this process of rapid association: distill your notes down to their essence.
- Every time you take a note, ask yourself, “How can I make this as useful as possible for my future self?”
- Your notes will be useless if you can’t decipher them in the future. Think of yourself not just as a taker of notes, but as a giver of notes—giving your future self the gift of knowledge that is easy to find and understand.
- Express
- All previous steps are geared toward one ultimate purpose: sharing your ideas, your own story, and your own knowledge with others.
- Personal knowledge Management exists to support taking action—anything else is a distraction.
- A common challenge for people who are curious and love to learn is that we can fall into the habit of continously force-feeding ourselves more and more information, but never actually take the next step and apply it.
- Information becomes knowledge only when we put it to use.
Capture: Keep What Resonates
A Second Brain gives us a way to filter the information stream and curate only the very best ideas we encounter in private, trusted place. Think of it as planting our own “knowledge garden” where you are free to cultivate your ideas and develop your own thinking away from the deafening noise of other people’s opinions. Maybe you are already a diligent organizer, but you’ve fallen into a habit of “digital hoarding” that doesn’t end up enriching your life.
Creativity depends on a creative process.
The twelve Favorite Problems, inspired by Nobel Prize-winning physicist Richard Feynman
You have to keep a dozen of your favourite problems constantly present in your mind, although by and large they will lay in a dormant state. Every time you hear or read a new trick or a new result, test it against each of your twelve problems to see whether it helps. Every once in a while there will be a hit, and people will say, “How did he do it? He must be a genius!
His approach was to maintain a list of a dozen open questions. Feyman’s approach encouraged him to follow his interests wherever they might lead. He posed questions and constantly scanned for solutions to long-standing problems in his reading, conversations, and everyday life.
Ask yourself, “What questions have I always been interested in?” These could be practical, questions about life, nature, relationships, or career—everything.
Having Curator Mindset
When you come across a insightful material like blog post, book, podcast, youtube video, or anything else, your first instinct might be to save the entire material. Might be you will bookmark or save to watch later. The worst part is, those will be there forever without you read or watch. Even you consume it entirely, in the future you’ll just have to spend all the same time to reading or watching it again, since you’ll have forgotten most of the details. This is why it’s so important to take on a Curator’s Perspective. Thiking like a curator means taking charge of your own information stream, instead of just letting it wash over you. The more valuable you can be with the material you capture in the first place, the less time and effort your future self will have to spend organizing, distilling, and expressing it. Here are four criteria to help you decide exactly which core of knowledge are worth keeping:
- Does It Inspire Me?
- Inspiration is one of the most rare and precious experiences in life. Keep a collection of inspiring quotes, photos, ideas and stories.
- Is it Useful?
- Sometimes you come across a piece of information that isn’t necessarily inspiring, but you know it might come in handy in the future. It costs nothing to keep these information around, and it might end up being the crucial missing piece in a future project.
- Is It Personal?
- One of the most valuable kinds of information to keep is personal information—your own thoughts, reflections, memories, and mementos.
- Is it Surprising?
- We have a natural bias as humans to seek evidence that confirms what we already believe, a well-studied phenomenon known as “Confirmation Bias”
- Surprise is an excellent barometer for information taht doesn’t fit neatly into our existing understanding, which means it has the potential to change how we think.
- By saving ideas that may contradict each other and don’t necessarily support what we already believe, we can train ourselves to take in information from different sources instead of immeadiately jumping to conclusions.
Ultimately, capture what resonates
Emotions organize—rather than disrupt—rational thinking.
- Dacher Keltner and Paul Ekman, “The Science of ‘Inside Out’ ”, NY Times, July 3, 2015.
When something resonates with us, it is our emotion-based, intuitive mind telling us it is intersting before our logical mind can explain why. I often find that a piece of content resonates with me in ways I can’t fully explain in the moment, and its true potential only becomes clear later on.
The stress was an automatic response that occurred because the intuitive mind realized something was wrong—long before the conscious mind realized anything was amiss.
- Stephen Wendel, Designing for Behavior Change: Applying Psychology and Behavioral Economics (Sebastopol, CA: O’reilly Media, 2013)
The authors’ conclusion: “Our intuitive mind learns, and responds, even without our conscious awareness” If we ignore that inner vocie of intuition, over time it will slowly quiet down and fade away, and the other way around.
The Surprising Benefits of Externalizing Our Thoughts
Your Second Brain gives you a place to corral the jumble of thoughts thumbling through your head and park them in a waiting area for safekeeping. It is not only for perserving them for the long term, but there are also benefits.
First, you are more likely to remembering information you’ve written down in your own words. Known as the “Generation Effect”.
Thinking doesn’t just produce writing; writing also enriches thinking.
There is even significant evidence that expressing our thoughts in writing can lead to benefits for our health and well-being. One of the most cited psychology papers of the 1990s found that “translating emotional vents into words leads to profound social, psychological, and neural changes.”
Organize: Save for Actionability
Having one single place that is easy to use, easy to undestand, easy to create, and easy to maintain is absolutely key point of Second Brain. We don’t need complex, sophisticated systems to be able to produce complex, sophisticated works.
The Cathedral Effect: Designing a Space for Your Ideas
Your Second Brain isn’t just a tool—it’s an environment. It is a garden of knowledge full of familiar, winding pathways, but also a secret and secluded corners. Gardens are natural, but they don’t happen by accident. They require a caretaker to seed the plants, trim the weeds, and shape the paths winding through them. Once you’ve created this environment, you’ll know where to go when it’s time to execute or create.
Organizing for Action: Where 99 Percent of Notetakers Get Stuck (And How to Solve It)
If we are already great at capturing ideas, shortly we’ll face a new problem and start asking ourselves a question, “How all of these writings matters to my current stage of life?”. That problem usually comes up because we organize it not “near” enough to our current needs. Imagine you have your notes inside the most matter thing that you are currently working on, not before, not after. But now. There are universal categories to organize our notes that we can overcome this challenge; PARA.
How PARA Works: Priming Your Mind (and Notes) for Action
- 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.
Distill: Find the Essence
Use our notes to drill down to the essence of the stories, research, examples, and metaphors that make up our own source material. THis is the moment we begin turning the ideas we’ve captured and organized into our own message. It all begins and ends with notes.
Quantum Notetaking: How to Create Notes for an Unknown Future
Your job as notetaker is to preserve the notes you’re taking on the things you discover in such a way that they can survive the journey into the future. That way your excitement and enthusiasm for your knowledge builds over time instead of fading away.
