I swear some people out there be building their note-taking system like NASA engineers building the next rocket to send us to the next habitable Earth.

Note-taking is the practice of taking notes. That's it.

You don't need to melticulously crafting your system like Hikaru Nakamura planning 18 moves ahead of how he should interact with his girlfriend.

Get what works for you.

And stop overthinking over notes.

(And if you need an example of dead-simple note-taking, James Clear stores his notes in a multi-hundred Google document)
