@dominickjosephluna: "Check it when it comes in" feels responsive. It aged my receivables 11 days. Ran a 30-day A/B on my inbox. Block A: open on every ping. Block B: 9am and 3pm windows only. Same clients, same work. The predictable number: context-switch cost. 94 min/day vs 22. A 72-minute gap. The attention tax is well-documented. The decisive one wasn't on my calendar. Days from job-done to invoice-sent went from 7.2 to 2.1. Receivables aged 11 days under the reactive regime. The money arrived a billing cycle later. Invoicing lives in the batch window. Reactive mode starves it. The responsiveness tax isn't on your calendar. It's on your bank. Build without permission.
