The "winds of change" is a common phrase that refers to the forces, actions, and influences that lead to an important change. It comes from a speech in 1960 by the British prime minister Harold Macmillan. Ex: Do you hear that? It's the winds of change. => A change is about to happen. A quote from the movie Monsters Inc. Ex: There is a wind of change in the voters' attitudes this election.
