Exactly: the ability to detect bullshit more quickly is unfortunately an ability not appreciated by many companies. It isn't just SV that has this problem. Those that tend to thrive in these environments past 40 are those who have instead learned play the imperfect system aggressively for their own benefit.
Along with that, I think an important value is just not taking wrong ideas personally. So some junior engineer wants to run off and do something that might cause you a head ache. Let them do it and learn from it. Your goal in life can't be to minimize everything that causes pain.
Oh, sure, but I'm not referring to that. It is more likely bullshit from upper management, from even older people...who lost touch with reality long ago.
