watching kids during uninterrupted play you can see intelligence playing with itself
contrary when watching adults at their work space they pretend to act intelligent whereas in reality they at best act clever but actually what you can observe is conditined mind at (hard) work.
usually there is a shift when childrens intelligence changes into conditioned adults cleverness.
it´s called school! i
t´s not only school but a conceptualized understanding of how life is supposed to work that want creative, intelligent children to adapt by loosing their innate capacities and authenticity.
as an adult you will meet this crossroad of change later in life when you experience emptiness inside, when you discover that you have been fooled by the concepts that you have believed in.
