The core
Pressure makes diamonds. Diamonds are forever. You are different now.
The second your eyes crossed those three lines, you read them — and reading is the thing that lays a record down. You didn't agree to it and you can't take it back; it's already too late to un-read them. That's the shape this page is about, and it just ran on you.
Those three lines aren't claims to argue with. They're pointing at a shape — and that shape is the real idea. The words just carry it.
So here is the shape. To make a diamond you take carbon — the same soft, smudgy gray stuff that's in a pencil — and you bury it, crush it, heat it, and hold it under all of that for an enormous stretch of time. What comes out the far side is the hardest thing we know of. And then it fans back out — into rings, into inheritance, into myth, into the actual word forever.
Now look again at the three lines, because each one names one part of that shape.
Pressure makes diamonds is the funnel — the burying, the crushing, the heat, all those forces narrowing inward on the carbon. Diamonds are forever is the bottleneck: the single hard form that survived all of it. You are different now is the fan-out — the rings and inheritance and myth it spreads into, and right now, that downstream is you.
Pressure makes diamonds. Diamonds are forever. You are different now.
You read those three lines differently this second time — not because I'm telling you to feel anything, but because you know what they're pointing at now, and you didn't a few paragraphs ago. Same three lines, read through what you've picked up since. That's the whole shape. If it landed, come on through. If it hasn't quite yet, there's no hurry; the three lines are still up there, and they'll keep.
