In three words I can sum up everything I've learned about life — It goes on.

The line distills a stoic, unsentimental wisdom: whatever one’s joys, losses, ambitions, or crises, time and ordinary life continue moving forward. It can be read as consolation (grief does not stop the world; one can endure and continue) or as a bracing reminder (no single triumph or disaster is final; the present will be overtaken by the next day). The emphasis on “three words” underscores the speaker’s claim to hard-earned simplicity—an attempt to reduce the complexity of experience to a single, durable fact. Its power lies in its neutrality: “It goes on” can imply resilience and renewal, but also indifference and inevitability.
