Having to be a hero once could happen to anybody.
But absolutely refuse to work with anyone who makes a habit of it.
Heroism is an error condition: it means that problems were allowed to get bad enough that extraordinary intervention was required to address them.
It's symptomatic of a failure to understand and preempt hazardous situations, and implies either an inability to conduct operations safely or a lack of planning.
@munin The famous military maxim is
“Prior Planning & Preparation Prevents Piss-Poor Performance”.
Part of that first P triplet is *risk assessment*, including both questioning assumptions (safety, reliability, predictability), and considering unexpected events, complications, or failures. This inverts “what could possibly go wrong” complacency, so it becomes a powerful tool.
