7. “Rest on One’s Laurels.”
Meaning: To be completely satisfied with what you’ve already achieved and have no desire to improve.
Background: Laurel wreaths, like the one pictured above, were status symbols in Ancient Greece. They also symbolized victory. Game winners were presented with the wreaths, and resting on one’s laurels initially meant something more along the lines of a victory speech, not the negative connotation we have with it today.
