Less worries other than survival. So called cultured man has worries such as- which girl should I shag, how can I make more money by bullshitting people into seeing value in god awful crap/unnecessary products that have flooded the marketplace since WWII, how will people perceive me if I reduce my standard of living, why can't I look and feel like everybody else, how can I get the funds to have a "doctor" fix me so that I can cut down on my sleep, consume more, and acquire more validation + resources.
I could go on all day but you see where I am going with this. We are chronic overthinkers with very trivial problems, held in captivity with the primary drive/motivation to life being substituted with the need to conform and impress others. That sucks up all your energy and only makes you more miserable.
