Lucas and Luna unpack a deceptively simple weekly practice that prevents boundary erosion before it starts. Instead of reacting to overcommitment after the fact, Lucas describes the five-minute check-in — a structured, recurring appointment with yourself to review what you said yes to, what drained you, and what your week ahead actually requires. Luna pushes back: isn't this just more calendar overhead? Lucas explains why this micro-routine beats traditional boundary repair, citing research on the vigilance cost and the specific triggers that signal boundary drift. They explore how one midlevel manager at a Fortune 500 firm used the check-in to cut unnecessary projects by 40 percent without a single difficult conversation. The episode closes on the hardest question: are you willing to see the data your own life is giving you? No guilt, no rigid rules — just a practical, low-friction tool for anyone who's tired of defending boundaries reactively.
