Rivers.
There are rivers inside your brain. Real ones.
Not rivers you dip your feet into. More like water molecules slowly diffusing through tissue.
When your mind wanders back to something that already happened or ahead to something that hasn’t it’s not just random.
It’s following routes.
In open space, water spreads everywhere.
In the brain, it doesn’t.
It travels along pathways.
The same ones, again and again.
After a while, those pathways strenthen.
Some get deep. Easy to slip into without even realising it.
Others stay shallow. You almost never go there.
Like true rivers. Some run for miles and carve out whole landscapes. Others only show up after a storm and vanish.
There’s a network of these routes underneath your inner life.
Memory. Imagination. Turning things over in your mind.
You notice them most when things get quiet.
People talk about brain regions like they’re separate boxes.
But that’s not really how it works.
It’s about connections. How activity flows.
If you tried to picture it, it wouldn’t look like a machine.
More like terrain shaped by time.
Some channels cut deep.
Some barely there.
A few that don’t quite flow right.
Some architecture you are born with and others you carve yourself.
And it’s always changing.
Use a route, it gets stronger.
Let it sit, it fades.
You don’t feel this happening.
But it’s happening all the time.
So when your mind keeps circling back to the same thing, the same worry, the same memory, there’s a reason underneath.
Not fate.
Just a path worn in.
You’re not just your thoughts.
You’re the routes they tend to take.
