But how do you account for things like cycles of violence and PTSD? I have veteran friends that, sure, could handle being shot at better than me, but on the other hand I can go to a fireworks show without worrying about having a public breakdown. Or I got friends that suffer for lack of the structure the military provided and just veg out now, picking fights at the bar for a little excitement.
Hell I guess you can describe them as "hard men" but I wouldn't want to be that way and it doesn't seem to make you more successful in modern society.
People with mental health issues need help and support. Just because there’s a pithy saying, doesn’t make it universally beneficial to have suffered hardship.
Not sure what else you’re expecting? I’m not advocating imposed hardship, just trying to give some context for why it can often lead to a more robust and driven person. It’s clearly not universally true.
I imagine there are lots of veterans that are able to cope and have become more robust. But there will always be mental health aftershocks, because that’s why it was a hardship in the first place.
