What Is A Second Brain & Why Do You Need One?

Neon Sign of Human with Brain - Obsidian Second Brain

A second brain is an organized structure that acts as a database about your life. It contains information like tasks, thoughts, ideas, and important dates, and helps you unburden your brain, so you can focus on essential tasks. There are various digital notebook applications you can use to organize your thoughts or projects in your second brain. 

Some examples are Otio and Obsidian. Key components and practices of a second brain include note-taking, organization, using digital tools, creating a personal knowledge base, developing a capture workflow, search and retrieval, integration, and continuous iteration. 

Reasons for Building a Second Brain

Building a second brain can improve your productivity by unburdening your brain of unnecessary information. This allows you to focus on creation and action. A second brain is an organized structure, allowing you to find information quickly through querying and filtering. If you wish to share your knowledge, export it, or back it up, it can be easily done because everything is externalized through your second brain.

What Is Obsidian?

Imagine you are an expert in the area of Obsidian Second Brain. Obsidian, as a markdown editor and reader, allows you to build what is known as a “vault”. In your vault, you can organize and store all your files while creating connections and interactions among them. From your computer’s perspective, your vault is just a folder where you save your markdown files. 

One of the greatest strengths of Obsidian is how it operates locally on your computer, leveraging folders and markdown files for seamless performance. To install Obsidian, visit the official website or search for it on major operating systems like Windows, Linux, macOS, Android, or iOS.

Why Build A Second Brain In Obsidian Specifically

You may or may not want to pay a monthly subscription to maintain your second brain. The good thing about Obsidian is that it’s a free note-taking app. Of course, there are some paid add-ons (like Obsidian Sync or Obsidian Publish), but those are not necessary at all.

Obsidian Allows You To Build Your Second Brain Across All Platforms

The main competitive advantage of Obsidian is that it works on all major platforms. On mobile, you can download their Android and iOS apps. On Desktop, you’ll find native apps for Windows, Mac, and Linux.

Obsidian Is Your “Offline” Second Brain

Deep work doesn’t happen when you’re connected to the internet. This is why productivity geeks use internet-blocking apps or unplug their routers when it comes to getting things done. Obsidian allows you to build your second brain on- and offline.

Setting up your second brain in Obsidian is easy and straightforward. 

  • Begin by downloading and installing Obsidian on your computer. 

  • Launch the app and create a new vault, naming it "Second Brain." 

  • Create seven key folders within your vault: Projects, Areas, Resources, Archives, Attachments, Daily Notes, and Templates. 

  • Adjust some settings, such as the default folder for daily notes and templates, for optimal organization. Consider customizing the colors if desired.

Start Taking Notes and Organizing

With your second brain set up, start creating your first note within Obsidian by going to "new" and selecting "create new note." Utilize the "backlinks" feature to make connections between your notes by referencing other notes within double brackets. This feature is powerful for creating a web of interconnected information. By following these steps and utilizing backlinks, you can begin building and organizing your second brain effectively in Obsidian.

Projects are multi-step tasks that you plan to complete soon. These could be research assignments, work projects, or even mundane chores. Projects align with goals - without a project, a goal is just a dream. Projects without goals are hobbies. 


Areas represent the next window of actionability. They are not to be confused with projects, though people often do. Areas are long-lived, with many tasks that repeat at regular intervals. For example, managing finances is an area. Areas are standard-oriented, not goal-oriented. They are where we store information relevant to routine activities.


Resources store information you are curious about but have no immediate plans to act on. Richard Feynman called these 12 Interesting Questions. Resources move the time horizon out even further than areas.


Archives are where things go that are not being worked on, do not fit into an area of life, are no longer interesting, or are no longer relevant. Completed projects, resources that have lost interest, or outdated areas are placed here. Archives ensure that you never lose information, but you can remove it from your visual clutter.

Best Practices For Building A Second Brain In Obsidian

  • When building your Second Brain, the first step is to select the right tools and platforms that will cater to your individual needs. 

  • Make sure to consider how you like to work and what kinds of information you'll be storing in your Second Brain. 

  • There are various tools available, such as Obsidian, Roam Research, and Evernote. Each tool has its own unique features, so it's important to choose one that aligns with your preferences and requirements. 

  • I recommend taking the time to explore different options and features before making your decision.

Strategies for Effective Information Categorization and Retrieval

Once you've chosen the right tools for your Second Brain, the next step is to develop strategies for effective information categorization and retrieval. To do this, consider how you'd like to organize your notes and create a system that works best for you. For instance, you might want to use tags, keywords, or folders to group related notes together. 

It's essential to establish a consistent naming convention that will help you quickly find the information you need. By organizing your notes systematically, you'll make it easier to retrieve and leverage the knowledge stored in your Second Brain.

Regular Maintenance for a Useful Second Brain

To ensure that your Second Brain remains up-to-date and useful, it's crucial to establish a regular maintenance routine. Set aside time each day or week to review, update, and add new information to your Second Brain. 

By regularly maintaining your Second Brain, you'll keep the information relevant and accurate. Consider revisiting your notes periodically to reinforce your memory and retrieve valuable insights. It's also essential to back up your data regularly to prevent any potential loss.

Integrating Your Second Brain into Daily Life

To derive maximum benefit from your Second Brain, integrate it into your daily life by making it a part of your routine. As you go through your day, consider capturing thoughts, ideas, and insights in your Second Brain to solidify your learning and enhance your creativity. By integrating your Second Brain into your daily life, you'll be able to leverage the stored knowledge in various aspects of your personal and professional life. Consider creating a habit of reviewing and updating your Second Brain regularly to reinforce your learning and boost your productivity.
