Building a Cathedral of Temporal Wisdom
Tiny thoughts on the value of personal knowledge systems
voiceover by ElevenLabs.
I’ve often wondered what it would feel like to speak directly with my past ‘selves’ in a way that allows a real exchange of insight across time.
What would the 19-year-old me say about some of the questions that are holding 27-year-old me in a chokehold? What patterns would he recognize that I might be too overwhelmed to see right now?
I was able to materialize that by building a digital portal from a corpus of more than eight years of entries from a personal journal of quotes recorded from thoughts, conversations, overhead remarks, films, books, and songs that helped me interpret the situations I was navigating at the time.
Over 500 of these entries were originally written in a small notebook I’ve carried with me since 2018, recording things that were relevant to some questions I had, even if I couldn’t yet articulate their weight.
Carrying the notebook around worked fine until parts of it started to get ruined as water spilled on it and almost erased years’ worth of personal archives.
Because I don’t always have the book on me, it’s also impossible to consult it at the exact moment I want to. And even when I do find it, searching for the most relevant quote is its own mini‑odyssey as I have to sift through hundreds of entries before landing on the one that speaks directly to my question.
I’ve come to see these sorts of interactions with personal troves as a form of temporal wisdom: guidance from perspectives recorded across different moments of one’s life.
Rather than relying only on the limited vantage point of who we are today, temporal wisdom emerges when past reflections and present experiences meet, creating continuity between who we once were and who we are becoming.
At first, the physical notebook was a private ritual of building a personal wisdom bank and preserving the nuggets I collected over the course of my life to, at some point, potentially weave into my memoir—if I live long enough to write one. But as the entries piled on, I realized I was unintentionally constructing something larger than a ‘compendium of wisdom,’ as I’d titled the notebook.
What I was building was a cathedral of perspectives archived over the course of many years, with each quote I recorded tied to a specific moment.
Revisiting those quotes years later felt less like reading pretty sentences and more like reading how a younger version of me was trying to, in his own way, build an independent understanding of the world.
Using Claude Cowork, I turned screenshots of pages from that journal into a single spreadsheet of quotes. After 30 minutes with my girls Lovable and Claude Code, I transformed the Excel sheet into an interactive platform hosted on Vercel that I now call my Wisdom Cathedral: a private platform I use to allow my past reflections to actively participate in shaping present thinking.
Let me talk you through how it works.
In this example, I sent the platform the thought:
“I’m torn between leaning into a romantic connection or letting it slowly fade. I’m equally scared of getting hurt as I am of hurting them, as I am of never trying. HELP!”
Typical shower thoughts, you know?
It then searched across my entire journal and generates a response connecting journal entries from different periods of my life into coherent advice for my current self. Rather than offering generic ChatGPT-style advice, it reframes my thought through the lens of my own recorded notes, surfacing connections that I honestly would’ve missed.
It goes a step further by concluding with thoughtful reflective prompt that invites me to interpret the significance of what I am experiencing rather than rushing to move past it.
In this format, the cathedral also functions as a living journaling companion. Throughout the day, as I interact with the platform, it synthesizes my questions and reflections into the “Journal” tab, creating a record of what I was thinking about that day and a summary of the targeted advice I got.
As someone who cares about recording my day but struggles with finding time to sit down and journal, having an auto-generated daily journal has been such a game changer!
My Cathedral’s daily “Knock” feature surfaces an unexpected fragment from the archive as a small ritual of inspiration that often feels uncannily relevant to whatever I happen to be navigating at the time.
The “Insights” feature shows me the broad themes of the wisdom nuggets in my journal as well as a top-line view of some of my most frequently asked questions.
My favorite feature though is “Wrapped”, which aggregates all the questions I have asked over the course of the year and identifies the dominant themes shaping my intellectual and emotional life, allowing me to see not only isolated moments of reflection but the broader arcs of what I have been learning and thinking about.
My experience with my wisdom cathedral showed me that wisdom (the thing I’m most in search of) is earned through deliberate cultivation.
For me, that’s been my 8-year accumulation of thousands of small observations layered over time that allows for patterns to emerge. But without that initial recording, those wisdom nuggets would’ve vanished, and I’d have had to learn those same lessons over again, more times than necessary.
Recording and revisiting those reflections creates connective tissue between my past and future self, consolidating insights from the past so I can make decisions in the present with extra context from my wishes for the future.
Sometimes it surfaces wisdom that’s screaming too loud ngl. But I still take it. I like that it helps me stay consistent with who I said I was going to be.
For the site, I chose the title of “cathedral” to capture the idea that, just like medieval cathedrals, cultivating wisdom takes years of thankless effort to realize. Sometimes even one lifetime isn’t enough.
Cathedrals like the Sagrada Familia were begun by one generation, expanded by another, and sometimes finished centuries later by people who would never meet the original architects. They did it just for the sake of continuing what was started.
Each group of builders contributed stones with the understanding that they were participating in something that extended beyond themselves.
I think personal knowledge systems work in a similar way.
Every recorded note or reflection is a stone placed deliberately into a structure that will only fully reveal its meaning or value when it attaches itself to a future-state context beyond the grasp of our present selves that’ll breathe new meaning into it.
I now treat documenting as a long-term architectural design practice that helps me build the intellectual scaffolding to support the thinking of my future self.
AI is truly the accelerant for me here.
For the first time, I was able to go beyond cataloging years of personal reflections to being able to also interact with them, query past thinking, surface forgotten insights, and compress years of trial and error into a reflective conversation.
Building my wisdom cathedral got me excited about the potential of AI to transform personal archives from static repositories into active collaborators in the process of self-understanding and meaning creation—two critical levers for combatting the ‘four horsemen of despair’ (which I wrote about here).
To savor life, then, is not only to live it fully but to also preserve it thoughtfully.
What cathedral are you going to build and what stones do you need?
I wrote the first draft of this essay for ‘AI for Human Flourishing’, a class I took in my 2026 winter quarter at Stanford. It’s been edited to sound less academic (used here as euphemism for “stuffy”).
This week’s content catalog
📚: ‘Thinking in Systems’ by Donella Meadows (cos I think systems thinking is going to be one of the most cardinal skills of our generation. More on this in another note.)
🎶: ‘BULLY’ - Kanye’s new album (is ‘separate the art from the artist’ still a thing in 2026?)
🎬: Fate/strange Fake on Crunchyroll - it’s a new anime I didn’t think I’d enjoy, but it’s been giving me life lately.
💡: I’ve been following OpenAI’s nine-figure acquisition of the TBPN podcast and what it could mean as a new template for tech-media partnerships as well as the risk of a new format of disseminating AI propaganda (at a time when we really could use less of that). I have my thoughts, but time will tell which it’s gonna be.
This is brilliant to read. I recently gained access to my old Microsoft note, and I found all my journals/notes and it was such an emotional interaction with my past self. Your article also reminded me of Jcole 's "Bomb in the Ville" where he spoke to his past self.
I guess my bother in building this capsule is this: I may get stuck in the wisdom of old self, and perhaps miss out on my current self. In Sandman's Second season, (imo the best ever TV series made), the new dream of the endless encountered this same challenge. He was faced between building his legacy as the new dream or stick to the previous dreams. Without giving a spoiler if you haven't watched it, he made a decision, an untraditional one; one that required him to ask himself how much his past self played a role in his current self.
I find what you have done an incredible and admirable feat that requires meticulous details and documentation; but for me, the cathedral will serve more like a hug to me , and reminder of myself than a source of wisdom or guidance.
This is really brilliant. I’ve been needing a better, more organized way to track my thoughts… definitely going to try this.
