Obsidian for Beginners: How to Start Your Second Brain

I have a folder on my laptop with 847 notes in it.

Most of them are half-finished. Some are just a single sentence I typed at 2am. A few are fully fleshed essays that never went anywhere. And scattered among them are maybe 50 notes that I actually use regularly — the ones that contain ideas I've returned to again and again.

For years, that folder was a mess. Finding anything took longer than it should. Connecting ideas across notes was almost impossible. I had knowledge, but I didn't have a system for it.

Then I started using Obsidian.

This post is what I wish someone had told me when I started. No fluff. No "you're about to transform your thinking." Just: here's how to actually begin building a second brain with Obsidian, and why it matters.

Why Your Notes Are Probably Failing You

Before we talk about Obsidian, let's talk about why most note-taking systems don't work.

Here's the trap: most people take notes reactively. They hear something interesting, jot it down, and never look at it again. The note goes into a folder (maybe), gets a tag (maybe), and then disappears into the void. Six months later you vaguely remember writing something useful about, say, content frameworks — but you have no idea where it is or how to find it.

The result? You keep relearning things you've already learned. You have the same conversations with yourself. You write first drafts from scratch because the research you did three months ago is buried somewhere you can't find.

This is the problem a second brain is supposed to solve. But most "productivity systems" just add more complexity without fixing the core issue.

The real question isn't what tool you use. It's how you structure your notes so they actually serve you later.

What Is Obsidian (And Why It Stands Out)

Obsidian is a note-taking app. But unlike Notion or Evernote, it's built around one powerful idea: your notes should connect to each other.

In most apps, a note is an island. In Obsidian, every note can link to any other note. When you link two ideas together, Obsidian creates a visible connection — a bidirectional link. You can click from one note to another, follow the trail of your own thinking, and discover connections you didn't know existed.

It also stores everything as plain Markdown files on your computer. This means your notes aren't trapped in someone's cloud service. They belong to you, forever, in a format that will be readable decades from now.

That might sound technical, but it matters. I've tried apps that locked me in, changed their pricing, or just… disappeared. With Obsidian, I own my notes. That's not a small thing.

The Practical Start: How to Actually Begin

Here's what I see happen a lot: someone downloads Obsidian, feels overwhelmed by the options, creates a dozen folders, and then abandons it after a week.

Don't do that.

Start with one folder and three types of notes.

Here's the system I started with — and honestly, I still use something close to this:

1. Fleeting Notes

Quick captures. The thing you think of in the shower. The quote you want to remember from a podcast. The half-formed idea at 11pm.

Rules: write it down fast, don't worry about formatting, and process it within a day or two. Fleeting notes are a inbox, not a destination.

2. Literature Notes

When you read something worth keeping — an article, a book chapter, a newsletter — write a note summarizing what stood out to you. In your own words. With the source cited.

Don't copy-paste quotes. Write what the idea means to you.

3. Permanent Notes

These are the core of your system. Take the ideas from your fleeting notes and literature notes, and write them as standalone thoughts. One idea per note. Link them to other permanent notes when you see connections.

This is where Zettelkasten comes in — the method developed by German sociologist Niklas Luhmann, who used it to write 70 books and 400 academic articles. His secret: every note was atomic (one idea), written in his own words, and connected to other notes.

The Simplest Workflow to Actually Follow

I know productivity systems can feel like a second job. So here's the absolute minimum viable workflow:

Morning or evening, 10 minutes:

1. Look at your fleeting notes from the last 24 hours
2. Turn the useful ones into permanent notes
3. Link each new permanent note to at least one existing note
4. Delete or archive the fleeting notes you didn't use

That's it. You don't need a complex folder structure. You don't need the perfect tags. You just need to capture, process, and connect.

The linking is the key part. When you link a note about "content consistency" to a note about "creative confidence," you're building a map of how you think. Later, when you're writing about either topic, Obsidian will show you that connection — and suddenly you have an insight you didn't have before.

One Feature That Changed How I Think

Before I wrap up: if you only use one Obsidian feature, use backlinks.

Backlinks are notes that link to the current note. So when you're reading a note about, say, "writing systems," you can see every other note in your vault that mentions or links to it. You discover ideas you'd forgotten you had. You find connections between things you wrote months apart.

This is the "second brain" part working. Your brain makes connections by proximity and repetition. Backlinks let your notes do the same thing.

A Note on Malaysian Context

If you're in Malaysia and you're thinking about building a second brain, here's the good news: you don't need anything fancy. Obsidian is free for personal use. It runs on any laptop. And the system I described above works whether you're a marketer in KL, a student in Penang, or a creator working from home in Johor.

The principles are universal. The implementation is yours.

Ready to Start?

Here's what I'd suggest: download Obsidian tonight. Create one folder called "Notes." Create your first three notes — one fleeting note about something you're working on right now, one literature note from something you read recently, and one permanent note about one idea that matters to you.

Link them together.

Then tomorrow, add one more.

That's how you build a second brain. Not with a perfect system, but with a starting point and the willingness to come back to it.

If you want a deeper dive into specific note-taking methods — Zettelkasten, PARA, or how to migrate from other apps — I've got more posts coming on this. But start here. Start small. Start now.
