The other pole is that you cannot control your reactions, but you can try to control the world. This is much easier to fit into a consumerist framework.
On a purely human level though, you should go find some veterans with PTSD and tell them they're just not working hard enough at being stoic.
Is it your take that every person in therapy for PTSD so wasting their time?
Much of mental trauma is about acknowledging it, and learning to live with it. There is no cure for PTSD, even Ketamine is short acting, not a long term solution, and indeed Ketamine simply helps you sit with the suffering in a different light.
But there are treatments. Last I read exposure therapy and EMDR were the two main ones. I don't think I'd be a big fan of exposure until the reactions have been significantly reduced, but everyone is different. EMDR didn't do much for me, but Internal Family Systems did. CBT is also great for some people.
