Why Your Whole-Ass-Personality, Changed During Puberty

 My answer will differ from the others, even though the other explanations have truth.

Assuming you live in the Western-world, and more-specifically the United States, your childhood (true) personality was replaced by an egocentric-personality. This does not mean that you are selfish or conceited though. On the contrary, it means that your personality was changed so that your concern would be refocused on how other people see you, instead of how you see yourself.

This may sound horrible to you, because it is.

Did I mention that this change to the way you see (and enjoy) the world, was done on-purpose?

It may sound like a conspiracy-theory, but it actually happened to you, and continues today.

It was done to you through what is called “Factory-schooling”, which was developed first in Europe, as a way to efficiently turn children into cog-like adults, who would work in the newly-developing Industrial-Economy.

Which was bad enough. But, because all generations of teachers, from that point on, have been trained by Factory-schooling; they see this horriible-system is seen as “normal" and even “good".

Which is why any changes to it will have to be forced, by concerned-people that are outside of that system, and the government that runs it. Concerned-people like most of you readers (hint).

Note: during the intervening 200-years, some ugly appendages have been added to this already-awful branwashing. Which include:

-the teaching of white-supremacy as being biologically, biblically, and moral-truths.

-Presenting Consumerism as a proper, patriotic, and “normal”; first by corporal-punishment and flowery-description, then by the classic 1950's-2000 “Educational-videos", and currently, (and perhaps most-underhandedly) through websites, including all social-media! Look them up, your school is on twitter, and trying to stagger into Tik-toc.

-teaching war as being a “fact of life”, and then introducing R.O.T.C., (and later; cash-"Bonuses" to impoverished-kids, under-served kids, and kids of military-veterans.

-and more.

So, in conclusion, your personality changed because; adults with childlike-wonder, and independent-dreams don't give their money to monsters.
