Writing is thinking

Why keep notes at all. Not for the aesthetic Notion dashboards, not for productivity theatre, not to build some "second brain" that you'll never read again. I've thought about this a fair bit, since I ended up building a notes app, and the best answers I found were all pointing at the same thing.

Paul Graham put it most directly - "Writing is thinking. In fact there's a kind of thinking that can only be done by writing." He quotes Leslie Lamport, the Turing award winner - "If you're thinking without writing, you only think you're thinking." (paulgraham.com/writes.html)

In an earlier essay he goes further. Half the ideas that end up in his essays are ones he thought of while writing them. And the uncomfortable corollary - someone who never writes about a topic has no fully formed ideas about it, however much they believe otherwise (paulgraham.com/words.html).

This matches my experience exactly. Every serious note I've written - an investment memo, a braindump on what to build, even a rant - changed its own conclusion midway. I'd sit down convinced of something, and three paragraphs in, the argument would fall apart on the page. The gaps don't show when the idea sits comfortably in your head. Writing drags it into the light where it has to actually stand up.

There's a famous Feynman story on this. A historian visiting him called his notebooks a wonderful "record of his thinking". Feynman corrected him sharply - the notes are not a record of the thinking, they are the thinking. The work happened on the paper. I find that framing changes how you treat your notes entirely. They stop being storage and become the workbench.

The Indian angle on this comes from The Art of Bitfulness by Nandan Nilekani and Tanuj Bhojwani. Their first principle for living with devices - use them as mirrors, not windows. A window is scrolling: looking out at everyone else's life, opinions, outrage. A mirror is writing notes to yourself, journaling: looking at your own mind. Same glass slab, opposite directions. They go as far as prescribing journaling as a form of meditation, and Nilekani keeps separate devices for creating, curating and communicating just so the mirror doesn't quietly turn into a window.

That distinction explains something I'd felt but never articulated. Five hours of screen time can leave you drained and anxious, while thirty minutes of writing notes leaves you calmer and clearer. Both are "screen time". One is a window, one is a mirror.

My own practice is unglamorous. Daily notes - plans, rants, half ideas, meeting notes. Most of it is garbage and will never be read again, and that is fine. The reading was never the point. On the days I write, my head is quieter and decisions come easier. On the days I don't, the same three worries just circle in the background like autorickshaws looking for a fare.

So my answer to why keep notes - you don't take notes to remember things. You take notes to find out what you actually think. The remembering is a side effect.
