Psychologists have a term for it: Mental Toughness ("MT")
... researchers agree, MT is particularly worth promoting among the young, a stance that seems at least somewhat at odds with today’s self-care narrative. Says Chawla, “I would define mental toughness as grit. Tenacity. And a fairly big chunk of that is having some discipline over your own impulses—doing things even when your mind is objecting. This idea is now reviled in mainstream culture in favor of approaches such as, ‘be gentle with yourself.’ [But] if you’re always gentle with yourself you will stagnate and grow weak and fragile.” If our goal is to uphold and not erode mental toughness, it is surely unhelpful to applaud iconic role models for extolling fragility.
