Oh yes, you’re absolutely right. It’s an impossible goal to reach.
But there’s shortcuts to understanding the thinking, thanks to the fact that we’re educated similarly and ‘tend to’ follow stereotypical patterns.
The scripts people use without even realizing it makes it a LOT easier to understand other people’s thinking processes. Perfectly? No, not at all. But well enough from a broad zoom view, and the more you engage with people different from you, the more you understand yourself.
In the end, all I’ll be doing is understanding myself and my capabilities as all of this ‘understanding’ will be taking place in a single place in the Universe: within myself.
So, I’m trying to maximize it.
