Mailman motto hidup

I think you meant to ask "What is the mailman's motto for living?"

The answer is: "Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds."

This is the motto of the United States Postal Service (USPS) and is often attributed to the ancient Greek historian Herodotus. It is meant to convey the dedication and perseverance of postal workers, who will continue to deliver mail and packages regardless of the weather or other challenges.
