rest on his laurels

The phrase "rest on his laurels" refers to a situation where someone becomes complacent or satisfied with their past accomplishments or successes, leading them to stop making efforts or striving for further achievements. It originates from the ancient tradition of awarding laurel wreaths (made from the leaves of the bay laurel tree) to victorious individuals, particularly in art, sports, or academics. Resting on one's laurels implies relying solely on past glories instead of consistently seeking improvement or pursuing new goals.
