I try my best to be extremely disciplined about my diet.

In this remark Brzezinski frames diet not as a temporary regimen but as a practice requiring ongoing self-regulation. The emphasis on “try” and “my best” acknowledges the difficulty of maintaining strict habits amid a demanding schedule, while “extremely disciplined” signals a belief that consistency—rather than occasional intensity—is what produces results. Read more broadly, the line reflects a common contemporary wellness ethic: personal health is treated as something managed through deliberate choices and routines. It also subtly positions discipline as a form of professionalism and self-mastery, suggesting that bodily maintenance is part of sustaining performance and public presence.
