That's the basis of social-belonging and other mindset interventions.[1]
For example, when you encounters difficulty as a freshman in college, do you think "I don't belong here", or "everyone has difficulties - I can get help, work hard, and succeed, like I've done in the past". Students who feel like they belong, build stronger support networks, more readily get help, feel better, and so. Both narratives then do feedback, and outcomes diverge. So surprisingly small interventions, to nudge the initial interpretation, like an hour in high school, or an essay at the beginning of a course, can have a surprisingly large impact.
I wonder if the future will look back our current lack of mental hygiene interventions, the way we now look back at the 1800's lack of physical hygiene interventions. Something like, well, it took a couple of decades, but NYC finally stopped politically-connected brewers from killing hundreds of children with adulterated milk from sick cows.[2]
