What appliance repair taught me about debugging software

Repair work taught me to slow down. A washer that will not drain, a dryer that overheats, and a bug in production all punish the same habit: jumping to the most obvious answer too early.

The loop is the same: observe the symptoms, form a theory, test the cheapest thing first, and keep the customer or teammate informed as the facts change.

That background is why I like software that is inspectable. Logs, metrics, validation checks, and clear failure states are the software version of a multimeter.
