Theodore Roosevelt said this quote
“ In order to succeed we need leaders of inspired idealism, leaders to whom are granted great visions, who dream greatly and strive to make their dreams come true; who can kindle the people with the fire from their own burning souls. The leader for the time being, whoever he may be, is but an instrument, to be used until broken and then to be cast aside; and if he is worth his salt he will care no more when he is broken than a soldier cares when he is sent where his life is forfeit in order that the victory may be won. ”
