The quality or state of being certain in oneself and in one's abilities is called what?

The quality or state of being certain in oneself and in one's abilities is referred to as self-confidence. Self-confidence encompasses the belief in one’s own capabilities to succeed in specific situations or accomplish tasks. It stems from recognizing one's strengths and having a positive mindset toward challenges. This confidence can significantly impact performance and decision-making in both personal and professional contexts.

Self-esteem, while related, primarily pertains to how one values oneself overall, including self-worth and feeling deserving of happiness. Self-awareness involves understanding one’s emotions, strengths, weaknesses, and motivations, which can contribute to developing self-confidence, but it does not directly define the certainty in one's abilities. Self-reliance refers to the ability to depend on oneself for support or decision-making, which is more about independence than confidence in one's skills. Each of these concepts is important for personal development, but self-confidence is specifically about believing in one’s capabilities.
