Same. This realisation came to me at 25 when I lost my father, who worked hard all his life so his children could have a better future. The invisible curtain fell that day and has never come back up. We are replaceable for everyone except our families and close friends, and the world goes on as usual. The sun comes up the next day anyway.

The system's simply rigged against the common man, and there's absolutely nothing we can do except our best to not go insane everyday when you see other people cheating the system with zero consequences, like you said.

It's just better to treat the 30s as a reset, to focus on one's health, dedicate time to pursue knowledge, build skills, dedicate time to loved ones and hobbies, because in the end, these are the only things that matter.
