My mom has always said that if I get a big head, she’ll take me out of this business as quickly as I got into it.

Moretz credits her mother with keeping her grounded amid the distortions of early fame. The “big head” idiom signals ego and entitlement; her mother’s blunt promise to “take me out of this business” frames acting not as an identity to be indulged but as a privilege contingent on character. The line also hints at the unusual power dynamics of child stardom: parental oversight can function as a moral safeguard against industry pressures, public adulation, and the temptation to equate success with personal worth. In effect, the quote presents humility as a form of protection—both for her career longevity and for her private self.
