> [!quote] 'Your brain is for having ideas, not for holding them' --[[Allen, David. Getting Things Done.]] A system designed to capture and enhance knowledge. [[da Vinci, Leonardo|Leonardo da Vinci]] had a "commonplace book"; think of this as similar. [[Forte, Tiago|Tiago Forte]] may be the most famous person to call it a "Second Brain", and I'm drawn to that description over some of the others. I have two separate systems for this, that I break up into… - [[Long-term memory]] - [[Obsidian]] (and [[Obsidian Publish]], which you're using to read this). - [[Short-term memory]] - [[Rocketbook]] [[Working memory]] reserved for [[Human brain]] (and vice versa). ## Considerations - [[A note is a unit of thought]] - in theory, I could make a separate note for "Considerations for Personal Knowledge Management", but another consideration is… - [[Notes should be practical]] - if a note does not have a purpose, it should not exist. [[Forte, Tiago, 2022. Building a Second Brain]] says [[Save that which is useful]]. - [[Prefer specialization over generalization]] - this system is purely for notes, not to-do's, calendar items - Journal entries and/or daily notes haven't worked well for me so far, but I plan on experimenting with the concept of making [[Daily notes function as entry notes]]. - [[Digital gardens need pruning]] - pages will appear, disappear, move, etc. Think of it like [[Decluttering]] for the brain. [[Eliminate that which does not serve a purpose]] - [[Aurelius, Marcus. Meditations]] is a model I would like to emulate with [[50 - Permanent Notes]], though it will also include observations about society in general. ## Approaches Used - [[Zettelkasten]] involves [[Luhmann, Niklas]]'s famous "slipbox" to create linked notes. - [Johnny Decimal](https://johnnydecimal.com/) provides a folder cataloguing system ([[Central Hub]] will give you more details as to how I have organized this) - [[Linking Your Thinking]] - itself influenced in some ways by [[Zettelkasten]], just updated for [[Digital age]]. ## Other Examples of "Second Brains" In no particular order: - [Andy Matuschak's notes](https://notes.andymatuschak.org/About_these_notes) - [Nicole van der Hoeven's notes](https://notes.nicolevanderhoeven.com/Fork+My+Brain) - [Obsidian Community Vault](https://publish.obsidian.md/hub/)
