I didn't realize it at the time, but everyone of the same seniority level, but a few years older, already realized not to give a single fuck about anything beyond their immediate sphere of influence. They had already learned that the work truly did not matter, and at a moment's notice they'd be tossed aside as person if given enough reason.

So, don't hope for much if you can't really control it, or spend your time gaining control, as in agency, over decisions that are actionable. Otherwise, burnout is on the horizon, because your expectations and devotion are way higher than you might get out of it, but the stress is maxxed out.

The parent here is perfectly on the money.

I'd also extend this to other areas of life. Probably try not to involve yourself too much with things that you can't influence, or things that you think people should care about but really don't. Not that they aren't inherently good, but you'll grind yourself down trying for nothing specific.
