The Light and Dark Side of Confidence

"Believe in yourself!" is the central command of the self-help industry. But assurance can slide into arrogance, or worse.

Self-Esteem

Possessing little self-regard can lead people to become depressed, to fall short of their potential, or to tolerate abusive situations and relationships. Too much self-love, on the other hand, results in an off-putting sense of entitlement and an inability to learn from failures.

Extroversion

Extroverts make up about three-quarters of the American population, and as such come in all stripes. They zip through the world in search of novel experiences, social connections and leadership opportunities. Extroversion is a core factor of personality and is difficult to modify.
