How to Build a Second Brain?
The perfect digital brain app does not exist. But who said we can only use one? Let me help you to save your best ideas, organize your learning, and expand your creative output.

There is one certain thing nowadays. Life is complicated, full of responsibilities. Family, work, keeping in touch with our friends — all of this requires our attention. And in the circle of life the faster we go, the more things we miss. How to take care of all aspects of your life without neglecting one? That is why a year ago I decided to build the digital brain, to live my life with no exceptions.
All of these YouTubers you watched, articles you read, they are all about being productive, managing your time efficiently, and doing all the things that you need to. And they are right. To help with that, developers designed apps for us. And in 2020, the number of productivity apps is so big that it is hard to keep on track. At least it was for me, because I was searching for a perfect productivity app for almost a year.
The perfect app — you may ask what I was searching for. Well, I hoped to find the app that makes it possible to organize family, friends, and job-related responsibilities. App in which I can take notes (both handwritten and not), save books I read, movies I saw, connect everything so it would be easy to navigate, control my budget, university — everything. But the fact is — the perfect app doesn’t exist. And like I said, it took me a year to realize that.
Today, I can proudly say, that I’ve my personalised, developed the second brain system. And second brain system connected with daily habits, spending time on studying, constant learning new things makes me happy. Makes me feel creative.
My Second Brain
My system is based on 4 apps. Imagine them as pillars, that keeping the whole construction — my system. Apps are Notion, Notability, Obsidian, Bear. And here’s how I learned to use them.
