Reddit mentions of The Neurotic's Guide to Avoiding Enlightenment: How the Left-Brain Plays Unending Games of Self-Improvement

>no one tried to tell my that my thinking is wrong

It's a difficult task, because the way our brains work makes personal experience supersede external information that contradict it, even when scientifically, objectively, our experience is... not "wrong" per se, but so incomplete that it veers into "wrong" teritory. I teach people how to get along with people, which is mainly applied psichology and neurology (specifically social neurology), so I come against this feature (it's not a bug, it's a feature) every time. For reference: Daniel Kahnemann's work. For reference: Chris Niebauer's book.

Your brain dupes you (it meakes you wrong, giving you the impression you're right) in several key areas relevant to our discussion here:

1. What You See Is All There Is: our brains operate on the assupmtion they have all the info needed to make good decisions and reach true conclusions, neglecting that there are swathes of information that might be / are relevant and that finally change the outlook completely.
   
2. Our Left-Brain Intepreter has the task to keep the story in our heads logically consistent, not correct. As such, it will gladly add to reality, or substract from it, only to keep the story. Please see this and this.
   
3. To accomplish this task, the LBI resorts to cognitive biases like overgeneralization, personalization, confirmation bias etc.
   
4. Its work is so powerful and so well hidden from conscience that most people, when confronted with science, will readily deny science ("well, that might be true but not for me") than accepting our thinking might be flawed.
   
   In your case, in order to examine what biases are in play and what is their result, I'd start questioning the hidden meaning of your use of notions like "chad", "betabux" and such. It speaks to overgeneralization (with a heavy serving of dehumanization) and confirmation bias.
   
   Humans are unique. There are, of course, trends (sociology doesn't exist for nothing) but so far no human being looks and act exactly like another human being always and in all aspects; more, humans change over time: experience, opinions, world views and behavior shift as time passes. That would be the first step I'd take if I were you: stop working with archetypes and start looking for tiny differences. The world will get extremely rich if you do that.
   
   TL;DR: you're wrong, but your brains won't let you see that and you have to voluntarily challenge it to improve your life quality.
   
   Edited to add: and I didn't even touch the issue of cultural and social norms and conditioning, learned helplesness and many other phenomena that interfere and change all the stuff above.
