So it's exactly right. The job of the brain is to take novel things and say, hey, if this is relevant and I need this, I'm going to burn it down into the circuitry so I never have to think about it again. Like bicycle riding. When you're first learning, you're paying attention to your torso and your legs and you don't know what you're doing.

When you get good at it, then you can text on your phone, you can talk to someone while you're biking, because it's now part of the machinery of the brain.

Exactly.

Exactly.

Exactly.

Oh, nice. Oh, I like that. Yeah, yeah. Yeah, that's exactly right. And what's interesting, by the way, I talked about this in the Brain Plasticity course and in my book, LiveWire.

What's interesting is that given who you are and what you've already packed down into your machinery, that determines what is relevant to you for the next thing, such that there's a million things you could learn or could pay attention to at every moment, but you're only going to... take on those things that are relevant to you and push them down into the unconscious brain as a result.

And we know, for example, the acetylcholinergic systems are involved in this process, which is to say they tag relevance. They say, hey, this is something that means something to you for whatever reason, who knows, but you really care about stamp collecting or genealogy or artwork or whatever it is that you care about.

And so then you go on these missions from the world and you take stuff in and you start burning that stuff down and it means something to you, whereas the rest of the stuff just goes.
