Self-confidence involves trusting in one's own abilities and feeling in control of one's life. Those with self-confidence understand both their strengths and weaknesses, have a positive self-view, set reasonable goals, communicate assertively, and can handle criticism. In contrast, low self-confidence can lead to self-doubt, passivity, sensitivity to criticism, and feelings of inferiority. While self-confidence levels may depend on the situation, having confidence in some areas and not others is common. Overall, one's self-confidence often reflects one's perceptions rather than objective abilities and perceptions can be imperfect.
