You’ve probably heard the old phrase “a rolling stone gathers no moss.” There’s no proof of exactly who coined the term or when, but it likely originated as a Latin phrase and it’s been well-known in English-speaking areas for several hundred years now. 

The basic meaning of the phrase is two-fold. A somewhat negative spin on the phrase is someone who is a rolling stone has no home and no roots, and can never “gather moss,” or collect anything permanent like wealth, family, or stability. A more positive meaning is a person who is carefree with no worries or commitments, or a perpetual traveler who is a “citizen of the world.”
