Because you listen. ;)
No, but seriously, I don't really have time to explain the id (inner mind) and I don't know everything, but that's what you want to look up. Just disregard anything about the software company (the company that made the game DOOM, and others, is called id Software, since bought by Bethesda, now owned by Microsoft).
There's a comment below (chronologically, before) that says meditation isn't about quieting the mind, but not reacting to it, or something like that. That's pretty much it, but you don't have to sit and chant or drink tea or any "meditation" stuff. (Meditation can be done whenever. I'm not making fun; rather, trying to dispel misconceptions about it. I meditate all the time.) So I've trained my brain to not "bug" me about every little thing. When it does, I tune it out. It isn't always easy, being that I'm on the spectrum (on the edge of it, high functioning, but still on it). But I make it work.
In layman's terms, because I really don't write about this, and haven't tried to explain it before, but I basically have two minds at any given time. It's almost like how multiple personalities are depicted in movies and TV. Or the TV show Severance, where people forget their outside lives when they come into work, and vice-versa when they go home. Except mine are both on all the time. One manages the "here and now" and the other basically fields everything else. Some would say "well that's just the ego and the id"; maybe so, but I feel I have some conscious control over it. Most people don't. Maybe I don't and I just think I do. Maybe I'm completely full of shit. Maybe you don't believe me. Maybe I'm wrong. Does any of it matter? Speaking this whole paragraph in the voice of Morpheus, as portrayed by Laurence Fishburne, in the film The Matrix. But I'm not holding out two pills, I'm just telling you how I see it. I'm not offering to take you on a journey though, we're just strangers on a train passing time in the cafe, I'm sipping my coffee on my way to work; you are... well, you know who you are and what you're doing as you read this. When you read it, I will be at work, I may be home, or it might be years from now and I may have passed on, but the me you're reading was the me who was sipping coffee typing on the computer before work on one random day among many.
Hope that helps. Or at least was entertaining. Or at least didn't waste your time.
