Adult maxxing is the act of going all-in on being a functional, responsible adult — optimising every corner of your life for stability, competence, and general maturity. Think batch cooking, building an emergency fund, flossing every day, and actually reading the terms and conditions. It's the grown-up version of self-improvement grindset culture, applied to the deeply unglamorous business of just having your life together. People who are adult maxxing usually do it with a degree of self-awareness and mild exhaustion, knowing full well that none of this is as exciting as it sounds.
