All these words describe a person who refuses to change their mind or back down from a challenge. Head-strongness can be both positive and negative, depending on the situation and the individual. While determination and tenacity can help a person achieve their goals, stubbornness and willfulness may lead to conflict or failure. Understanding and recognizing head-strongness in oneself and others can help to foster productive communication and avoid unnecessary conflicts.
