"Resting on Your Laurels": Being Complacent with Past Achievements

When someone is "resting on their laurels," it means they are complacent or satisfied with their past successes and are not actively striving for further improvement. 

This phrase originates from ancient times when victors in athletic competitions were crowned with laurel wreaths as a symbol of their victory. 

It implies a lack of motivation or ambition to pursue new goals or challenges.
