There is a fine line between confidence and arrogance. Every great leader must have an inner sense of belief and conviction, but when that veers into an obnoxious, detestable self-reverence, what they say and do lacks power and punch.
Great leaders possess both a natural gut instinct that they stick to and a humility to admit when they are wrong or lacking. Those moments of vulnerability and weakness are what make a leader relatable, someone who people want to follow, someone who people believe in, not because of rhetoric or fancy communication and a sheer force of will, but because they are real.
