Famous quotes containing the words early and/or work:
“Here is this vast, savage, howling mother of ours, Nature, lying all around, with such beauty, and such affection for her children, as the leopard; and yet we are so early weaned from her breast to society, to that culture which is exclusively an interaction of man on man,—a sort of breeding in and in, which produces at most a merely English nobility, a civilization destined to have a speedy limit.”
—Henry David Thoreau (1817–1862)
“... any citizen should be willing to give all that he has to give his country in work or sacrifice in times of crisis.”
—Eleanor Roosevelt (1884–1962)
