It wasn’t until I read How to Take Smart Notes by Sonke Ahrens that I realized almost everything I’d assumed about the Zettelkasten or “slip-box” note-taking method was WRONG.

This method gets a lot of attention for the results it gave German sociologist Niklas Luhmann. He used index cards and a unique numbering system — and for some of us, that’s all we know about it.

Now, there’s a lot of talk about creating a digital Zettelkasten with the help of text editors and apps like Roam Research, Obsidian, and Evernote… but most of us don’t know what that means. And if we want to build a “second brain” or become more prolific writers, we should know what Zettelkasten ISN’T — and, more importantly, what it IS.

So let’s expose the common misconceptions about Zettelkasten, and learn what it’s really all about (so we can implement it successfully!)…

Misconception #1: That we can take notes in exactly the same way we always have.

We mistakenly believe that Zettelkasten changes only how our notes are stored, and not how they’re created.
