Last week we found that there is very little overlap between how good people think they are and how good they really are. This week, we look at how confidence can motivate, get us off the couch, make us healthier, enterprising, decisive and help us live up to our potential. We also learn how doctors, entrepreneurs and whole economies can benefit from the right kind of confidence and the ways in which we can tell the good from the bad. In this edition of the Why Factor, Michael Blastland asks: why do we admire confidence?
