hitch your wagon to a star
Set high goals. The phrase come from an 1862 Ralph Waldo Emerson essay “American Civilization”: “Now that is the wisdom of a man, in every instance of his labor, to hitch his wagon to a star, and see his chore done by the gods themselves. That is the way we are strong, by borrowing the might of the elements. The forces of steam, gravity, galvanism, light, magnets, wind, fire, serve us day by day, and cost us nothing.” It used to be heard among other bit of avuncular or graduation speech advice. Then advice for the future became more specific, like “plastics” in the movie The Graduate. Nowadays, in this economy, your guess is as good as mine.
