Beyond Just 10K Steps: My Story
Let me tell you a personal story of how I used a second brain for personal growth. First of all, I highly recommend reading this article if you don’t know what a second brain is.
Back in June, I decided to join the popular challenge of walking 10k steps a day for a month. I had tried to do it before but every time, after the first two weeks, I got lazy and abandoned it.
This time, however, I decided to make a task in Brainfo, the personal knowledge management tool that I use, to help me stay motivated and get over the finish line.
Most will think that this is something to be done with a smart watch. And that is correct. But your smart watch cannot be your journal as well. This is where Brainfo comes in.
With Brainfo I:
- Tracked my daily progress with checkboxes and tasks,
- Wrote about my feelings, motivations and obstructions to doing the walk everyday,
- Stored podcasts, spotify playlists and other things to motivate me on the walks,
- Analyzed my mood and progress at the end of each week to see how I was doing.
This process was what kept me motivated and interested in this challenge and got me over the finish line.
Now, let’s learn some more unconventional ways you can use your personal knowledge management system.
Build a Dynamic Habit Tracker

Forget about the myth of 21 days to develop a habit. According to a study published on PubMed Central, the actual time is 66 days.
Your second brain tool can help you develop good habits and break bad ones with a dynamic, personalized approach.
Idea:
Your second brain tool can help you develop good habits and get rid of bad ones.
Why it’s different:
It’s not just a checklist, it’s a comprehensive system in which you can add different things to create a multimodal space that can serve several functions.
How to do it:
- Create a task, note, or page for your new habit.
- Dedicate a section to journal your feelings, collect motivational material, and generally anything that can help you stay on course.
- Create a goal and score sections and when you reach the finish line cross out the goal and give yourself a score.
- Keep a place for collecting all the habits you want to develop and review it once-a-month to see how you’re doing and if you need to go through the process again.
Benefits:
This method gives you creative freedom and deeper insight into your progress, making habit-building more effective and enjoyable.
Create a Decision Making Journal

It’s not something nerds do, it’s what great people like Benjamin Franklin did as well. Journaling your decisions and thinking process is an old and time-tested method for making better decisions.
Idea:
Use your second brain to make better, more-informed decisions.
Why it’s different:
It lets you see things from an outside perspective, with pros, cons, and other relevant data. You wouldn’t have to juggle several things in your brain anymore.
How to do it:
Create a template that has “Pros”, “Cons”, “Options”, “Consequences”, “Final Decision”, and “Review After X Months”.
Fill this template in whenever you want to make a decision and then decide.
Benefits:
Helps you make better decisions and creates a log of your decision-making process to be reviewed later and identify mistakes or biases or even strengths, improving the process.
Manage Your Personal and Professional Relationships

Making friends at work is not just about fun, it will also make you more productive. And if you want to make deep and meaningful relationships you need to know when is your coworkers wedding anniversary, or when their child will have their birthday, etc.
Idea:
Manage your personal and professional relations with your second brain tool.
Why it’s different:
You are not just storing contacts, you are building a network of people and adding details about them that helps your interactions with them.
How to do it:
- Create a space to add people, notes, and other relevant information.
- Write down little details about each person that are important to your relationship.
- Set reminders for things you need to do with them or their birthdays
- Expand and grow your database.
Benefits:
You will become a more thoughtful friend, family member, or coworker, someone that knows the people around them and remembers details about them.
Create a Hub for Project-based Learning

Project-based Learning (PBL) is shown to be more effective at long-term knowledge retention and applying knowledge in new contexts. That’s why you need a solid method to document and track your learning.
Idea:
Use your favorite second brain tool to boost your learning and collect everything in one, searchable, and structured place.
Why it’s different:
Second brain tools are amazing for learning and personal growth and are distinct from note-taking apps in that they give you a lot more structure and options to organize your data, instead of just collecting a load of information.
How to do it:
Create a project and fill it with resources, training material, a schedule and set of tasks, and a report or note section.
- Collect resources,
- Study them,
- Practice what you’ve learned based on your schedule,
- Make a summary or report of what you’ve learned and what you did with it (this should be something that easily reminds you of the whole session just at a glance).
Benefits:
Having a plan and structure boosts your learning. Learning alone and at home is notoriously difficult. Because we like to be in a learning environment and work with other human beings.
This method keeps you disciplined and efficient on your learning journey and at the end you will have a special synopsis or even a course that you’ve made during the journey and can refer back to anytime you wanted for a quick refresh.
Make learning an active process instead of passive consumption of data.
Build Your Personal Idea Factory

According to Steven Johnson, popular author and theorist, most people don’t get new ideas from Eureka moments, rather, it’s what he calls the “slow hunch”. It’s all the little things that you learn slowly and over time that lead to significant discoveries or breakthroughs.
Idea:
A digital brain is not just for storing ideas, it can connect them together and help you generate new ideas as well.
Why it’s different:
Your second brain can be the creative boost you need to conjure up new ideas. When it’s written down and/or visualized in front of you, with connections being made and everything being searchable, you can infer and develop new ideas without having to do all the hard work in your brain.
How to do it:
Review your notes regularly and draw connections between them and use second brain tools to create graphs and see everything at a glance.
Benefits:
This practice helps you generate new insights and see things that you most likely would have missed.
Conclusion
Apart from all the note taking and task management, you can use your second brain in unconventional ways such as:
- Dynamically tracking habits,
- Journaling your decision-making process,
- Managing your personal and professional relationships,
- Boosting your learning,
- Creating new ideas.
While you can use your second brain software to implement methods such as Zettelkasten for note taking, and PARA or CODE for project management, you can also use it in other ways for productivity.
I strongly recommend picking one of these five uses and trying it for a while to see how it’ll change the way you do things.
