Treat each productivity-table tile as a standalone linked document so visual elements become navigable knowledge nodes.
Briefing
A personal knowledge management system built in Obsidian turns a “periodic table of productivity” into a navigable network of ideas—so concepts don’t just get stored, they get actively connected, stress-tested, and internalized. The core move is treating each tile on the productivity table as its own linked document, then using Excalidraw-style drawings stored as Markdown to keep visual structure and written references in sync. With more than 10,000 notes in a local “vault” (a folder of Markdown files), the system makes it easy to flip between an editable drawing and the underlying notes that explain and connect it.
At the center of the demonstration sits a tile called “Choose your character.” The workflow hinges on how Excalidraw files can be opened in two modes: an editable drawing view and a Markdown view that contains the interconnected references. In Markdown mode, the notes beneath each tile act like a web of citations and conceptual links—so every visual element becomes a portal into a chain of supporting ideas.
The “Choose your character” tile then branches into a compass-based structure inspired by the “Compass of Zettelcasten.” Each reference is organized by direction to force perspective-taking: North for origins and larger categories, South for instances and examples, West for similar or supporting ideas, and East for competing or challenging ideas. In practice, hovering over elements in Excalidraw/Excalidraw Brain surfaces previews of linked concepts, and clicking a tile jumps back to the corresponding periodic-table entry. The result is a deliberate method for reducing blind spots: if nothing appears in the East, the system flags likely bias because contradictions and challenges are missing.
Several specific intellectual threads get placed into this compass framework. “Choose your character” is connected to James B. Carse’s finite and infinite games through the idea of playing roles—like an actress leaving one role behind and taking up new ones offstage. The tile is also tied to close reading and the notion of speaking in the author’s voice, plus StrengthsFinder-style thinking that emphasizes leveraging natural strengths rather than forcing roles that don’t fit. Additional links bring in PKM personality frameworks associated with Nick Milo and Thiago Forte, along with “imitation” as a route to outstanding results, connected to visual notes on extraordinary achievement and decoding greatness by Ron Freedman.
Beyond the compass, the system adds an “integration board” concept. Using a shared icon (curiosity, in the example), the creator explores multiple instances of the same visual symbol across different contexts, then maps the relationships between them. Gate numbers on connectors indicate how many links exist in each direction, making the structure measurable rather than purely aesthetic.
The closing claim is that this 4D PKM approach—combining visual thinking, compass-based perspective shifts, and integration boards—helps internalize concepts into a person’s mental landscape. The goal isn’t just better note-taking; it’s lasting change through repeated connection, summarization, problem-solving, and big-picture synthesis, with curiosity positioned as the differentiator that filters ideas and motivates the search for truth.
Cornell Notes
The system builds a “periodic table of productivity” inside Obsidian where each tile is a separate, linked Markdown document. Excalidraw-style drawings are stored as Markdown too, letting the user flip between an editable diagram and the written, interconnected references behind it. A compass framework (North/South/West/East) organizes links by perspective—origins, examples, supporting ideas, and challenges—so missing contradictions in the East reveal bias. An “integration board” then uses a shared icon (like curiosity) to explore unexpected but meaningful connections across contexts. The practical payoff is internalization: concepts become part of how the user thinks, not just what gets saved.

Review Questions
- When a tile is opened in Markdown mode, what specific advantage does that give compared with staying in drawing-edit mode?
- How would you use the compass directions to deliberately find counterarguments to a central idea?
- What does an integration board add that a simple list of references wouldn’t?
Key Points
- 1
Treat each productivity-table tile as a standalone linked document so visual elements become navigable knowledge nodes.
- 2
Store Excalidraw drawings as Markdown so the same artifact supports both editing and reference-rich note connections.
- 3
Use the Compass of Zettelcasten (North/South/West/East) to structure links by origins, examples, supporting ideas, and challenges.
- 4
Treat missing East links as a signal of likely bias because contradictions and competing ideas are absent.
- 5
Use gate counts to gauge how many connections exist per directional perspective, making the structure more observable.
- 6
Build integration boards around shared icons (like curiosity) to surface unexpected, meaningful relationships across contexts.
- 7
Aim for internalization—repeated connection and perspective-shifting—so concepts become part of how you think, not just what you store.
