Charisma is the ability to inspire followers with devotion and enthusiasm to a cause. It encourages disciples rather than independent persons. It is a way of investing oneself with authority over other rather than vesting others with authority over themselves.
It's true that charisma can make a person stand out for a moment, but character sets a person apart for a lifetime. You build trust with others each time you choose integrity over image, truth over convenience, or honor over personal gain. Character makes trust possible, and trust is the foundation of leadership. Character creates consistency, and if your people know what they can expect from you, they will continue to look to you for leadership. Over time, is it easier or harder to sustain your influence within your organization? With charisma alone, influence becomes increasingly more difficult to sustain. With character, as time passes, influence builds and requires less work to sustain.
My strong point is not rhetoric, it isn't showmanship, it isn't big promises-those things that create the glamour and the excitement that people call charisma and warmth.
