I over-modeled the biology and under-modeled my calendar

Before maintenance, I stress-tested every scenario: food noise roaring back, late-night grazing, weekends at my parents' house. Built rules. Protein at 7, kitchen closed at 9, snack drawer at work. The actual first month? The only wobble was a Tuesday with back-to-back meetings. I skipped lunch, then ate standing at the counter. That wasn't biology, it was a calendar bug. I'd optimized the scary variable and left the boring one unmanaged. Now I batch a lunch the night before and stop pretending Outlook is a meal plan. Did your big worry turn out to be something smaller and more logistical?
