To look at everything always as though you were seeing it either for the first or last time: Thus is your time on earth filled with glory.

The line urges a discipline of perception: to meet ordinary life with the heightened attention we naturally bring to beginnings and endings. Seeing something “for the first time” suggests freshness, curiosity, and gratitude; seeing it “for the last time” adds poignancy, humility, and an awareness of mortality. Together, the two perspectives counteract habituation—the dulling effect of routine—and turn daily experience into something luminous. The claim that this fills one’s time “with glory” frames glory not as public achievement but as an inward richness created by mindful attention and reverence for the fleeting present.
