Building A Second Brain as presented by Tiago Forte, one of the world’s foremost experts on productivity, is a systematic approach to creating a digital repository for organising and taking action on the abundant ideas you come across every day. While there are a range of products available to promote this concept, in this edited report Praburam Srinivasan, Growth Marketing Manager for ClickUp explains how AI can make the task easier with AI-powered assistant ClickUp Brain
Given the exponential growth in online consumption, remembering all the information you come across every day becomes impractical. Building A Second Brain (BASB) to consolidate this wealth of information in a single, accessible location can increase your productivity significantly.
Having a structured space for storing and organising information allows our minds the freedom to think, imagine, and be present in the moment. Moreover, when not burdened by the constant pressure of trying to remember everything, you are more likely to take the right actions.
While a recent survey shows that 34 percent of users operate with complete confidence in AI systems, a slightly larger group (38 percent) maintains a “trust but verify” approach.
A standalone tool which is unfamiliar with your work context often carries a higher risk of generating inaccurate or unsatisfactory responses.
This is why we built ClickUp Brain, the AI that connects your project management, knowledge management, and collaboration across your workspace and integrated third-party tools.
CODE and PARA
Forte introduced two crucial principles as part of building a second brain.
CODE: Capture, Organise, Distil, Express
This four-step method helps you organise information and turn it into concrete results:
- Capture: Gather information systematically from various sources, such as articles, videos, or other content. Using AI tools for note-taking, you can capture relevant information and insights
- Organise: Once information is captured, categorise and store it in a way that makes it easily accessible when needed
- Distill: Extract the essential insights or key takeaways from the captured information
- Express: Articulate and express the distilled information through note-taking, summarising, or even creating, content based on the insights gained
PARA: Projects, Areas, Resources, Archives
According to Forte, all the information in your life can be divided into just four categories: - Projects: This category is dedicated to the specific tasks or initiatives you are actively working on with all relevant information, tasks, and resources related to those projects. For example, your projects might include writing a report, planning an event, buying new furniture for your home, and learning to cook.
- Areas: Areas represent broader aspects of your life or work that encompass long-term goals or responsibilities. For instance, work responsibilities like product management and coaching teams, and home responsibilities like home, kids, finances, etc.
- Resources: This category is for valuable knowledge that may not be directly related to your project but relates to your areas of interest and might be useful in the future, such as reference materials, tools, or information. For example, information about personal finance, habit formation, growing herbs, wood-working, etc.
- Archives: Archives store completed projects, outdated information, or anything that doesn’t require immediate attention but may be useful for future reference
Benefits of Using BASB
Building your second brain helps eliminate the stress that comes with the continuous consumption of information. If you are juggling multiple priorities, the BASB method helps you break down complex projects into smaller parts, set milestones, and track progress, ensuring tasks don’t fall through the cracks.
You can use your digital workspace to create detailed project plans, track deliverables, and prioritise activities by urgency. When each step is visible and organised, you avoid last-minute chaos and delays.
Your second brain also becomes a valuable record of what worked, what didn’t, and how you overcame challenges — fueling better planning for future projects. Maybe months later, during a similar launch, you revisit these notes and avoid past pitfalls, saving time and improving outcomes
No information overload
Have you ever felt incredibly overwhelmed by the sudden burst of information you consume online? Let’s say in a week, you attend a series of webinars, read several articles on recent trends, and engage with online communities or discussions.
Your brain faces information overload and needs help organising and categorising information.
This is where the second brain methodology can come in. Without a proper system, you risk forgetting important details before you even realise it — and trying to connect the dots later is frustrating.
By using modern tools like note-taking apps, virtual whiteboards, mind maps, and second brain apps, you can retain important insights and communicate them effectively with your team.
For example, after attending a marketing webinar, instead of scribbling notes in random docs, you add the core takeaways to a structured folder in your second brain app. When it’s time to brainstorm campaign ideas, those learnings are ready — organised and actionable.
Effortless retrieval
Let’s be honest — no one wants to dig through scattered documents while preparing for a big presentation or making a time-sensitive decision. You need information to be accessible, contextual, and ready to use. Some examples may include:
- Preparing a strategy deck. You’re scanning through research reports, notes from past meetings, and industry benchmarks. In a high-pressure moment, the BASB method allows you to quickly pull key points from your digital workspace — no backtracking or context-switching required.
- Use mind-mapping techniques to organise your thinking visually, and jot down innovative ideas or angles during research. This structured flow ensures that when it’s time to create, you’re not starting from scratch.
- Another example might be where you are pitching a new product. With everything tagged in your second brain — past market research, customer pain points, tested messaging — you can build your story faster and with more confidence.
- BASB can assist in creative ideation. Creative thinking thrives when ideas are captured, stored, and revisited. When you have a constant flow of thoughts and inspirations, jotting them down and categorising them is key.
Central repository
BASB helps build a central repository of images, quotes, articles, and notes — so nothing valuable slips away. This collection becomes your go-to space during creative blocks or content planning. Some example include:
- You come across a brilliant analogy while reading a novel. You save it in your second brain under “storytelling techniques.” Weeks later, it becomes the hook for a potentially viral ad concept.
- You can also use interactive whiteboard templates for team brainstorming. Everyone works in the same space — no screen-sharing or clunky file exchanges — making collaboration seamless and fast.
How to Build a Second Brain
Building a Second Brain isn’t about collecting notes—it’s about creating a reliable system to think better, remember more, and act faster.
There are five clear steps, combining conceptual clarity with ClickUp’s practical tools
Step1: Identify your problems
The first step towards building a second brain is identifying your most common challenges. Do you struggle to retain valuable insights, apply what you’ve read, or act on scattered ideas?
Keep questioning yourself about the areas where you find yourself stuck. Jot down these specific challenges to ensure you capture the required information and use the right approach to building a second brain.
Let’s say you often hit a creative block. A Second Brain gives you a place to store ideas as they come to you, so you always have something to return to when your mind goes blank.
Once you’ve identified what’s holding you back—like scattered ideas or forgotten insights—it’s time to design a system that works for your brain.
Create a Knowledge Base Space. Start by creating a new Space in ClickUp dedicated to your Second Brain.
You can call it “Second Brain,” “Digital Vault,” or “Personal Knowledge Base.” This will be your master container— everything you store, organise, or revisit will live here. Use a distinct icon and color for your Space to make it easily recognisable in your workspace sidebar.
Step 2: Capture the right information
Now you know the challenges you must face using a second brain. However, it is crucial to capture the right information, as not every information is equally valuable. That’s where a brainstorming session with the right ideation techniques helps you gather the right information.
It is best to use diverse formats to capture information, such as notes, texts, images, links, audio recordings, and sketches.
Use ClickUp AI Notetaker to auto-capture conversations and meetings and record meeting discussions. Instead of scrambling to jot down ideas during important discussions, let the AI Notetaker record your Zoom, Google Meet, or Microsoft Teams calls and auto-generate summaries, action items, and transcripts.
You can instantly turn those insights into tasks, Docs, or folders in your Second Brain—without losing any context.
Create a recurring “Review AI Notes” task to process these insights weekly and decide what to keep, tag, or archive.
Within your Second Brain Space, create Folders that represent major domains of your life or responsibilities such as Marketing Strategy, Personal Development, Books & Reading Notes, Startup Ideas and Wellness & Habits
This mirrors the “Areas” and “Resources” sections from the PARA method and helps you segment knowledge meaningfully
If you want to incorporate brainstorming into your capture process create categories or themes for the types of information you want to capture. Identify actionable steps or tasks associated with the information you want to capture and use an AI tool like ClickUp AI to instantly generate ideas based on any topic— just type your prompt and get going
Summarise long notes, meeting transcripts, or documents automatically with ClickUp AI’s smart recaps, draft, edit, or reword content in seconds using ClickUp AI’s built-in writing tools
Start using ClickUp Brain:
- Use tags and keywords during brainstorming to identify key themes and concepts
- Use visual tools such as mind maps, diagrams, or concept maps
- Refine your capture process over time as your Second Brain evolves
Don’t wait for the “perfect moment.” Build the habit of capturing information as you encounter it — via note apps, voice memos, or quick-click bookmarks.
If you are still stuck try a brainstorming software or template inside ClickUp to structure your creative sessions.
Step 3: Choose the right tools and technology
Building a second brain is about organising, categorising, and retrieving information when needed. While you can spend hours manually tackling these tasks, investing in knowledge management software will make your job easier.
You could use ClickUp Docs to capture and organise notes or create documents for team presentation . Docs are your digital notebooks.
Inside each Folder, create Docs to store your thoughts, learnings, and inspirations. You can:
- Journal daily reflections
- Summarise YouTube videos or podcast episodes
- Organise book notes with headings, checklists, and bullet points
- Draft content or outline projects
Examples:
- A “Books I’ve Read” Doc with notes per book
- A “Workshops” Doc recapping online courses
A “Mental Models” Doc with decision frameworks
Different teams can easily collaborate on the doc and brainstorm together. Create a second brain that keeps everything intact for everyone. Editing in real time helps ensure that important ideas are not missed during discussions.
Connect ClickUp Docs to your workflow by linking tasks together; ClickUp Whiteboards help you take your brainstorming to the next level. This kind of visual collaboration is particularly helpful for remote or hybrid teams.
Combining this with the right brainstorming templates allows you to have some great ideation sessions with your team.
Lastly, organise your notes into categories, folders, or views so you can instantly locate the right information when needed.
Step 4: Create a structure that works
At this stage, you’ve collected a lot — but without structure, your Second Brain can become chaotic. That’s where organisation frameworks like PARA (Projects, Areas, Resources, Archives ) and CODE (Capture, Organise, Distill, Express) come in.
With the right visual tools, you won’t just store information—you’ll understand and act on it faster. ClickUp Mind Maps visually connect your thoughts, categorise knowledge, and restructure your workspace using drag-and-drop nodes.
You can map tasks and topics visually, modify project hierarchies without leaving your view and create, edit, and delete tasks directly from your mind map
Step 5: Schedule reviews
A Second Brain isn’t “set it and forget it.” You need to regularly reflect, refine, and resurface what matters.
Start with a simple habit: a weekly 1-hour review.
- Scan the overall structure of your Second Brain
- Review recent notes and captured content
- Check for project updates or changing priorities
- Link new content to existing themes
- Reflect on new ideas or mental breakthroughs
- Update deadlines, tags, and statuses
- You can use ClickUp Reminders or Automations to trigger weekly “Idea Review” tasks, prompt a monthly “Archive Sweep” or remind you of quarterly synthesis rituals
Enhance discoverability and retrieval by linking related Docs and Tasks internally, tagging content with #themes like #research or #insight and creating custom views—Kanban for readings, Lists for notes, Calendar for reviews You can use ClickUp Connected Search to find anything, instantly.
With consistent reviews and the right system in place, your Second Brain becomes a powerful thinking partner—not just a filing cabinet.
Common Challenges of Building a Second Brain
Even with a solid plan, building and maintaining a second brain comes with hurdles. Here’s what to watch for:
Information overload: The digital era inundates us with abundant information and deciding what to capture or discard becomes overwhelming. Let’s say you want to stay updated on the latest trends, research, and news. Even a quick Google search brings up dozens of articles, making it hard to choose what’s truly relevant. Without a clear strategy, you either over-save or miss what matters.
Just in case: You save every article you see “just in case.” Weeks later, you can’t find the one insight you actually needed.
Maintaining consistency amid procrastination: Maintaining your second brain takes consistency, but procrastination often leads to messy systems and neglected notes. If your second brain is just a scattered collection of Google Docs, it stops being useful.
The digital junk drawer: You start strong with neatly tagged folders, but skip updating them for weeks. Now it’s a digital junk drawer instead of a productivity tool. Your second brain shouldn’t become a digital graveyard. A weekly cleanup or review helps keep it alive and useful.
Choosing the right technology: The number of tools available, from Notion to Obsidian to second-brain apps with built-in AI, can be paralysing. You test three tools in one month but stick with none, leaving your notes spread across platforms and your workflows disconnected. Evaluate tools based on ease of use, workflow compatibility, and long-term sustainability. Don’t overcomplicate —start with what you’ll actually use.
Fear of failure: A common blocker is the fear of failure with the system — the worry that you’ll spend hours setting it up, only to abandon it. For example, you delay creating your second brain because you’re unsure of the “right” way. This fear of imperfection stops you from starting altogether.
Treat your second brain as a living system. It’s okay to start small and evolve as you go.
