Being eager is the state of being enthusiastic, excited, or motivated about something. On the other hand, the antonyms of being eager are states of disinterest or indifference such as being unenthusiastic, apathetic, lethargic, or uninterested. These antonyms suggest that one lacks the zeal to engage in a particular activity, or lacks the drive to participate in something that requires effort, time, or attention. People who are unenthusiastic tend to be passive and may lack the necessary skills to succeed in a particular endeavor. Conversely, those who are eager possess a positive attitude and are more likely to succeed because they have a strong desire to achieve their goals.
