Unfortunately, this is only half the story, because if you don't build adequate resilience and capabilities, you'll be traumatized by increasingly minor things.
Indeed, this is the easy half of the story. Yes, trauma traumatizes. It can lead to lasting damage. Easy to understand, seemingly easy to know what to do: try to protect people from trauma.
But what do you do to make people as resilient as possible, so they are less likely to be traumatized, without either traumatizing them or turning a blind eye to trauma that is being inflicted? That's the difficult half.
