There is a world of difference between the personality traits and behaviors it takes to be chosen as a leader and the traits and skills you need to be able to lead effectively.

Expertise increases self-knowledge, which includes awareness of one’s limitations. Conversely, the less you know, the less aware you are of your limitations and the more overconfident you will be.

This link between perceived confidence and competence is important. Although women are assumed to be less confident than men and some studies have shown that women appear to be less confident, a closer look at the research shows that women are internally confident. In fact, men and women are both overconfident—even if men are still more overconfident than women.

...we choose leaders by how confident they appear rather than by how confident or competent they are, we not only end up choosing more men to lead us but ultimately choose more-incompetent men.

Self-confidence is the strength to focus on what’s right instead of who’s right. It’s the strength to face reality. It’s the strength to admit mistakes, and the strength to change your mind. Self-confidence is what it takes to be on the right side of right.

Outcome over ego.
