"Take snappy snaps, stay calm, fix it right."
In a crisis, your calmness is more valuable than any one command.
Write scripts for tired hands and foggy brains. Recovery time is no time for guesswork.
Take frequent snapshots when in danger. Rollbacks are cheaper than regret.
You should never have to guess if a system is healthy. Status must be instantly visible.
Design for things to break. Build recovery in, not around.
When systems are down, think slower, type slower. Mistakes cost more than patience.
Every fix, every lesson, every runbook saves future you from suffering.
