What means expressing your ideas and opinions firmly and with confidence?

The term that describes expressing your ideas and opinions firmly and with confidence is "assertive." Assertiveness involves communicating one’s thoughts and feelings in a clear and respectful manner, ensuring that you are able to uphold your own rights while also considering the rights of others. This balance enables productive dialogues and fosters mutual respect in relationships.

In contrast, being passive typically refers to a lack of communication about one's own needs or opinions, often leading to unmet needs or feelings of resentment. Aggressive communication, on the other hand, involves expressing oneself in a way that may disregard the feelings and rights of others, often leading to conflict. Finally, being submissive often entails yielding to others' preferences or decisions, which can stifle personal expression and assertiveness. Understanding these distinctions is crucial for effective communication and healthy relationships.
