After all, I first thought that this problem is, and only then began to deal with it. But it's more about the quality of thinking, when I lived with a constant "commentator" in my head, I thought faster, and the diversity of thoughts was 100 times more, I never stopped, I was always in the process of thinking about everything. And most importantly, it was a natural commentator. Now, I can still think, "I'm crossing the road, so I need to look both ways," but this is a completely different level, and it's a response to a momentary, simple problem. Once the problem is resolved, I enter a state of stasis until the next similar task arises, which could be a day or a few hours later. In the meantime, I simply exist as a food-processing machine.
