Don't mistake zero-fucks with zero-cares. Staying cool while keeping your sleeves rolled up working on fixes is an absolute life skill. Knowing it's always "Same shit different pile" is maturity, not resignation. Working hard because you are a valuable engineer doing a good job, despite knowing that the world is full of chaos and nothing will matter in 5 years is called Professionalism.

Get paid, invest, be chill and fun to work with, enjoy your family and friends, go fishing or something.
