Capitalist bootlickers be out there telling you to study shit to boost your ability to do your job, and here I am studying Lie Group and Algebras and how to use Prolog because I fucking want to, even though they're completely *useless* to me as a healthcare professional.
Miss me with that productivity bullshit. Me and my myriad of interests don't have time for that.
Okay, maybe I exaggerate the "not because it'll be useful for me" bit. After all, I wanna be an ER nurse. Things that make me better at my job help society. If I can easily communicate with a deaf person using ASL, or with a recent immigrant using their language, that matters for more than just making some leech a bigger profit. It legitimately makes someone's life better, unlike whatever it is these bootlickers think you should waste your free time on.
Basically, learn whatever makes your life and other people's lives better, not what some capitalist or bootlicker thinks you should learn to make you more "productive".
Don't get me wrong, I do also study things that are useful to me. I'm currently trying to learn ASL. But even that shit is out of a personal interest (and desire to be able to communicate with deaf people on *their* terms), not because it'll be useful to me as a nurse.
