Some things cannot be changed; it's like asceticism, where you are
indifferent in a way to the fact that reality is what it actually is,
for instance things that the government does that you have no power to
change the law
itself.
I think the reason why I feel this now is pretty obvious: the nature of school cannot be changed by such a small grain of sand, it being me, or even the whole collective nature of students. Even if you collect all the students, in this world, they have little power compared to e.g. legislators! Students' minds may not have matured yet, and it is tragic that most cannot speak up or even be studied in research! I feel like it leads to survivorship bias in which the adults would no longer think that school is a big deal (already done) compared to work (what they do right now). Of course the intensity of the feelings would be stronger for something being experienced right now!
It’s a big part of being a stoic. And it is usually done to things that cannot be
changed, like past failures. Just doing so would relieve the brain a lot
because the brain will stop trying to do something it cannot do, which
is changing unchangeable things.
This view will help you with things that have already happened, which
can help prevent nihilism from regretting the past, which I see
happens frequently with older people.
There will certainly be things that, given your lesser knowledge tree at
past times, may not have turned out the ideal way.
And then it transitions to pragmatism: the education system and society may be
unfair, but complaining pretty much won't help. Rather, given
the circumstances, what actions can be taken? You will figure
out as you spend some time on problem-solving.
It might imply satisfication but maybe you still have some form of internal conflict making it hard to accept. You may honestly need to check out nihilism - and then maybe realizing that you may need to accept the deeper fact that some things are just unfair and hard to accept (Just-world fallacy)!
