What is the opposite of complacence?

The opposite of complacence is rooted in the idea of being overly content or self-satisfied, often to the point of neglecting potential dangers or challenges. Complacence typically signifies a lack of concern for possible future problems or the failure to improve one's situation due to a false sense of security.

Discontent is the correct choice because it embodies a sense of dissatisfaction or unhappiness with one's current circumstances. When someone is discontent, they are often motivated to seek change or improvement, which contrasts sharply with the passive acceptance often associated with complacence. Discontent drives individuals to be active in addressing issues rather than remaining idle.

The other choices do not align as closely with the concept of moving away from complacence. Indifference reflects a lack of interest or concern, but it does not necessarily imply an active desire for change. Concern indicates awareness and caution, which can coexist with complacence. Satisfaction suggests a fulfillment that is quite akin to complacence rather than its opposite.
