Humility is a prized attribute, and being called "most big-headed" is not a compliment. Antonyms for this term include modest, unassuming, humble, unpretentious, self-effacing, and low-key. These words describe individuals who avoid bragging, are not overly impressed with themselves, and do not seek attention. Instead, they act with humbleness and grace, showing appreciation for their strengths and others' qualities. People who possess these qualities often put others before themselves, genuinely listen to perspectives that differ from their own, and strive to be the best version of themselves while leaving room for self-improvement. In short, the opposite of most big-headed is someone who values modesty and authenticity.
