some therapist talking about how your 20s set up the foundation for the rest of your life, so wasting your time at 22/23/24 in casual relationships and service industry jobs is basically a massive waste of time and you have to get going on your future now now now until your eggs dry up at 35
This is just some old conservative Guy enforcing his personal values on the young. You can really live however the fuck you want and if some crispy old Guy disapproves, who gives a fuck?
'Grind' culture is basically just capitalist values, stimulate the economy and yadda yadda. They're not really looking out for anybody but themselves, their advice all comes back to their own wallet or their own visions for the future of society and culture.
I'm not saying pursuing money is bad because it obviously helps with general survival, but luck and circumstance factor too heavily into it for me to take all this grind bullshit seriously.
