Volunteering is so pervasive it's invisible. We take for granted all the things that have been pioneered by concerned, active volunteers.

Paul Revere earned his living as a silversmith. But what do we remember him for? His volunteer work. All activism is volunteering in that it's done above and beyond earning a living and deals with what people really care passionately about. Remember, no one gets paid to rebel. All revolutions start with volunteers.
