The happy have whole days, and those they choose. The unhappy have but hours, and those they lose.

The couplet contrasts two experiences of time. Happiness is figured as spacious and self-directed: the happy possess “whole days” and can choose how to spend them, suggesting agency, leisure, and an unhurried mind. Unhappiness, by contrast, compresses life into “hours,” a sense of scarcity in which time slips away unused or wasted—“those they lose.” The epigram implies that well-being is not only an emotion but a way of inhabiting time: contentment enlarges it, while misery fragments it and erodes one’s capacity to act. It also hints at moral responsibility, urging readers to reclaim choice and attention before time is forfeited.
