[Introverts,] the world needs you and it needs the things you carry. So I wish you the best of all possible journeys and the courage to speak softly.

Addressed to “introverts,” the line functions as a benediction and a corrective to cultures that prize loudness, speed, and constant self-display. Cain frames introversion not as a deficit to be overcome but as a form of carrying—inner resources such as reflection, careful attention, depth, and moral or imaginative conviction. “The world needs you” asserts social value, while “the courage to speak softly” reframes courage as the willingness to contribute in one’s natural register rather than mimicking extroverted norms. The phrasing suggests that quiet influence can be both authentic and consequential, and that self-acceptance is compatible with public participation.
