Famous quotes containing the words trail and/or difficulty:
“Most of us don’t have mothers who blazed a trail for us—at least, not all the way. Coming of age before or during the inception of the women’s movement, whether as working parents or homemakers, whether married or divorced, our mothers faced conundrums—what should they be? how should they act?—that became our uncertainties.”
—Anne Roiphe (20th century)
“In spite of all their kind some elements of worth
With difficulty persist here and there on earth.”
—Hugh MacDiarmid (1892–1978)
