Unlikely accomplishments are borne out of single-minded purposefulness. Future superstars don't get there by keeping part of their heart in reserve.

We tend to view confidence as a product of accomplishment rather than part of the process that leads there. But supremely confident people were confident long before they achieved anything.

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."

Bill Russell is one of the great names in basketball, an all-American... and the only athlete to ever win an NCAA Championship, an Olympic Gold Medal, and a professional championship all in the same year-1956...But Bill Russell had this one problem: He threw up before every game.

Great performers welcome pressure.

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

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.
