It's all depends on what you call the leadership. It's could be like in this sentence "in the land of the blind, the one-eyed man is king" but in whole spectrum one-eyed guy are hendicapt -> and seying about evryone can be leader i see like one-eyd guy story ;) Not everyone can be a GOOD leader and some perssonalitites have more or less pottential to be a leader ... and then would be nice to be aware those potential and develop it...
