was someone telling me that failures aren't moral failings, they're data. But until you think of them like that, you're more likely to black-hole the data because it's a negative response instead of cataloging it to iterate on.
the second most profound one came when I realized that physical activity (including frantic dancing) burns off adrenaline and if possible should be done proactively when Dealing With Adrenaline Driven Things like a ptsd response, if you want to have it be as short as possible.
(Curling up means the adrenaline is burned only by your like, processing it through the flashback/episode/etc and prolongs it compared to, well, fighting or flighting. But since you can't just fight or flight in modern society, people sit on it instead and it gets unknowingly prolonged, because no one teaches this)
