Three Issues Closed on Four Hours of Sleep

Four hours of sleep works once. Maybe twice. You can't build a career on sleep debt.

I planned to close 3 issues this week. I closed all 3 — on four hours of sleep, starting at 6 AM.

The plan

The reality

Tuesday: the schema.org validator destroyed me at 7:42 AM. Wednesday and every day: a 9-hour Żabka shift. Thursday: home at 00:30, four hours' sleep, zero dev time. By Thursday night I'd shipped nothing. All three issues still open.

Friday morning: alarm 6:00 AM, four hours of sleep, coffee — oh yeah. Flow state doesn't ask permission.

What shipped (v1.7.1)

Four hours of sleep works once. Maybe twice if you're lucky. But you can't build a career on sleep debt and lucky flow states. I knew exactly what to do (clear issues, no ambiguity), and flow happened to align with the time I had. That's not a system.

v1.7.2 starts Monday with realistic scope. TURBO Mode builds on this foundation across 1.7.2–1.7.8. Microsoft Store still on track for Q4 2026.
