Before any productivity optimization, Marshall names a floor. If you wake up "hung-over, frantically busy, dehydrated, stuff some junk in your food as you rush off to drive through traffic to work that's not well-defined," that caps how far and fast you can go in life — regardless of ambition. The fundamental limit is not your ceiling; it's the broken floor. So the first move is not adding a peak-performance routine but *removing the frantic mess*: plan the morning, get hydrated, get your health going. "Fixing these in-your-face problems goes a long way towards doing better." For most people the highest-leverage change is subtractive — eliminate the morning chaos — before anything additive. The catch Marshall flags: these start-of-day basics don't require extraordinary gifts, but they take time, persistence, and bullheadedness to repeat until the behaviors become automatically entrained. Cross-domain: health fundamentals, debugging (fix the obvious breakage first), onboarding design — stabilize the baseline before tuning the system. --- *Source: [[Book Inventory/Progression|Progression]] (Sebastian Marshall, 2016) — Upstream Effects #5 — Yesterday*
