He that lives not well one year sorrows for it seven.

A single year of bad conduct, wastefulness, or poor judgment may bring consequences that persist far beyond the original lapse. The proverb stresses that short-lived irresponsibility can impose a long period of regret and difficulty.

It advises foresight and steady self-discipline: present choices should be weighed against their lasting cost. Its numbers are a forceful contrast, not an exact timetable, emphasizing that consequences may outlast the behavior that caused them.

Use it as a moral warning when someone is tempted to sacrifice long-term welfare for immediate pleasure, neglect, or reckless conduct. It can also comment on the lingering burden created by a brief period of imprudence.
