Elevated levels of confidence are omnipresent among history's greatest overachievers. Benjamin Franklin, one of the most famous men in the world even before he signed the Declaration of Independence once lamented about humility, "I cannot boast of much success in acquiring the reality of this virtue."

All the great performers I have worked with are fueled by a personal dream.

Confidence is a resolute state of mind by which you believe nothing is impossible.

Great performers in all fields seem immune to what outsiders think about them. Their sense of themselves never depends on the feedback-positive or negative-they get from the environment.

Overachievement is aimed at people who want to maximize their potential. And to do that, I insist you throw caution to the wind, ignore the pleas of parents, coaches, spouses, and bosses to be "realistic." Realistic people do not accomplish extraordinary things because the odds against success stymie them. The best performers ignore the odds. I will show you that instead of limiting themselves to what's probable, the best will pursue the heart-pounding, exciting, really big, difference-making dreams-so long as catching them might be possible.

To be a top performer you have to be passionately committed to what you're doing and insanely confident about your ability to pull it off.

Great performers require a measure of confidence that would strike many as absurd, unfounded, and downright irrational. They believe in themselves utterly, without question, even when everyone else is questioning how good (or sane) they are.
