No one, in the year 1770, was better fitted than Samuel Adams, either by talent and temperament or the circumstances of his position, to push the continent into a rebellion. Unlike most of his patriot friends, he had neither private business nor private profession to fall back upon when public affairs grew tame, his only business being, as one might say, the public business, his only profession the definition and defense of popular rights.... the serious business of a man who during ten years had abandoned all private pursuits and had embraced poverty to become a tribune of the people.
