Introduction — On What I've Been Writing for Years

This is a follow-up to my previous post on Claude and MCP. Just sharing some recent thoughts.

Personally, I've always enjoyed keeping records and analyzing my own work. So for years, I've been logging my daily tasks, jotting down thoughts, hesitations, and impressions in notes. I've drawn on these records for reviews, analysis, and decisions on various projects.

The tools have shifted over time — Evernote, Notion, Logseq, Taskuma, and so on — but the habit itself, of writing notes into some app or tool, has stayed with me for years.

What Happened with MCP

I recently wrote about connecting Notion and Google Docs through MCP, and the results have surprised even me. I won't repeat the details here since they're in that post, but ever since I introduced MCP, the flow of information has accelerated dramatically. In particular, I'd been accumulating reviews, task management notes, and brainstorms in Notion for years, and letting Claude read all of this has shifted the meaning of what I'd previously written.

When I first started recording in Notion, it never occurred to me that it might be useful to AI. Of course — I had no way to imagine a time when AI would become this close to everyday life, used in this way. I was just writing for plain, analog reasons — "so I could look back later," "so I could organize my own thinking."

But the moment MCP made it all readable, the feeling shifted. It's as if my past self comes forward to help my current self. Claude answers my current questions while drawing on the reasoning behind old project decisions, or on impressions I'd noted at the time. I've had moments like that more than once now.

Thinking about it: the human brain's memory has limits — even the person who wrote something forgets it quickly. That's why I kept taking notes, leaving behind my thoughts and conclusions at each point in time as a record. And now, in the flow of conversation, AI reads from those records, distills them into a form that immediately fits my current self, and bridges across to me. Whether for grounding decisions or raising the quality of brainstorms and project work — my past self's accumulation comes through directly. That's the structure underneath all of this, and I only noticed it recently.

What I Noticed

When a new technology appears, many people tend to focus on its newness. New tools, new techniques, the sense that we have to do something new with them. I'm the same way — I catch myself thinking I need to add something new on top.
But this time, in my own case, what actually worked was the opposite direction. Using a new tool to draw out the old accumulation I'd built up over years, and to work creatively with it. That was the shape of it.

It wasn't that something new worked — it was that something old took on new meaning. That came as a surprise, and I wanted to write it down.

Maybe this isn't just my story.

The things I've built up over time. Things that look old, things that seem to have lost their value. Maybe the value didn't disappear — maybe there just hadn't been a reader for them yet. And now, there's something that can read across all of it.

Closing

To be honest, over the past few years, watching AI develop so quickly, I've had this worry — that what I've been doing for years might get replaced, that what I've accumulated might have been wasted. A vague anxiety that's been sitting somewhere in the background.

But this time, with MCP, what I'd been collecting in Notion started to do more for me than ever before. It wasn't wasted, I found myself thinking.

For my own part, I want to keep this perspective going forward — alongside chasing new tools, asking how I make the most of what I've built up over time.

Thank you for reading :)
