Better a thousand times careful than once dead.

Better a thousand times careful than once dead is a traditional safety proverb rather than a traceable literary quotation. It circulates as a piece of folk wisdom used to justify caution in situations where a single mistake can be fatal—travel, manual labor, warfare, or any hazardous work. The phrasing suggests oral transmission and practical instruction (often from elders to the young or from supervisors to workers), emphasizing that repeated vigilance is preferable to a single irreversible accident. Because it is proverbial, it typically appears in collections of sayings and in didactic contexts rather than in a single identifiable first publication or authorial moment.

The proverb argues for prudence by contrasting the minor cost of repeated caution with the irreversible cost of a single fatal mistake. “A thousand times careful” evokes habits of vigilance—checking, preparing, and avoiding needless risk—while “once dead” underscores that some consequences cannot be corrected or learned from afterward. Its force lies in the asymmetry between inconvenience and catastrophe: it is rational to tolerate frequent small delays or restraints when the downside is permanent harm. The saying is commonly applied to safety, travel, hazardous work, and any situation where one error can end a life or ruin a future.
