What Are Idioms About Luck?
These expressions use figurative language to talk about fortune, chance, success, risk, or events outside someone’s control.
Some describe good luck, others warn against relying on it, and a few suggest that preparation matters as much as chance.
In everyday speech, “idiom” is often used broadly for fixed expressions.
A proverb is a short saying that shares advice or a general observation, while an idiom usually has a figurative meaning that cannot be understood from its individual words alone.

How to Choose the Right Expression
Choose an expression that matches the kind of fortune you mean.
Use “a stroke of luck” for a fortunate event, “a lucky break” for an unexpected opportunity, and “luck of the draw” when chance determines an outcome.
For a string of setbacks, “a run of bad luck” is clearer than a phrase that treats misfortune as a certainty.
Pay attention to tone, too. “Just my luck” is often wry or sarcastic, while “fortune favors the bold” sounds encouraging. “Push your luck” is a warning; “be in luck” is a cheerful way to tell someone that an opportunity is available.
