There is necessary nuance to discuss between stimuli, thoughts, feelings, and unconscious reactions. And I reject wishing or intellectualizing away the realities of the human condition with an idealistic belief system. You can't necessarily control what you feel or how your body reacts if you almost get run-over by a car. Aspiring to become a Vulcan "Spock" seems an unhealthy goal, much as conforming to toxic positivity or toxic negativity. It's like: Why do people go to therapy? Often to unload their baggage to someone else, not to stuff more of it away and pretend it's not there. There's no "free lunch." That said, I think there is value in repeatedly stressing people near or past their breaking points, relieving burnout potential, and gradually increasing challenges to moderate an individual's stress response and build their confidence ("break them down and build them up"). Furthermore, the Marines train their leaders make to decisions with incomplete information under pressure. Stressful experiences help make future experiences seem less daunting.
