“To determine whether or not you have the ingredients to be charismatic, answer the following questions: What are your real feelings about who you are? What do you believe in? Do you have goals or a mission in life? Do you project optimism? Do others turn to you for leadership? Non-charismatic people spend their lives auditioning for others and hoping they'll be accepted. Charismatic people don't doubt their ability to add value to a situation, so they move forward with their mission.”

Context: All leaders are human. They get tired, angry, and jealous and carry the same range of emotions and frailties common to mankind. Most leaders periodically display them. The leaders I most admired were totally human but constantly strove to be the best humans they could be. Leaders make mistakes, and they are often costly. The first reflex is normally to deny the failure to themselves; the second is to hide it from others, because most leaders covet a reputation for infallibility. But it's a fool's dream and inherently dishonest. There are few secrets to leadership. It is mostly just hard work. More than anything else it requires self-discipline. Colorful, charismatic characters often fascinate people, even soldiers. But over time, effectiveness is what counts. Those who lead most successfully do so while looking out for their followers' welfare.

Variant: Ask yourself three questions and you will know who you are. Ask 'What do you believe in? What do you hope for? But most important - ask what do you love?
