> there is nothing new under the sun
that quote also makes sense, think about it
it doesn't mean we as humanity can't invent anything new, it means there're very limited set of phisolophy concepts, that were also known thousands years ago
if you have have decent knowledge of philosophy and literature, I doubt you can find any new concepts in movies and motivational speeches, because they operate on exactly same ground
there're still lot of things that can change you anyway though, but they're quite extreme
e.g. war, death of your relativies or children, intolerable living conditions, drugs, breakthrough in brain/AI research
