Quote by Theodore Roosevelt: “The joy of life is to be used for a purpose recognized by yourself as a mighty one.”

This quote suggests that true happiness and fulfillment come from dedicating oneself to a cause or mission that one deeply believes in. It implies that a life of meaning is not about ease, but about purposeful effort directed towards significant personal aspirations.

From his essay collection "The Strenuous Life," Roosevelt was advocating for a life of vigorous action and moral purpose. He urged Americans to engage actively in public life and strive for national greatness through individual effort and civic duty.
