A lesson they teach in $IVY_LEAGUE, "you all know whistle blowers don't end up well." Direct quote from $INFLUENTIAL_DUDE in response to $PUBLIC_THING.

Trust your gut. When it says leave, leave. Even if others encourage the opposite. Even if your extended family depends on your income.

Make the effort to build and maintain a strong social circle. Filter for integrity. Assiduously avoid those who distort truth for personal advantage.
