“Of what violences, murders, depredations, have not the epic poets, from all antiquity, been the occasion, by propagating false honor, false glory, and false religion?”
—Samuel Richardson (1689–1761)
“The working woman may be quick to see any problems with children as her fault because she isn’t as available to them. However, the fact that she is employed is rarely central to the conflict. And overall, studies show, being employed doesn’t have negative effects on children; carefully done research consistently makes this clear.”
—Grace Baruch (20th century)
“The feeling of being hurried is not usually the result of living a full life and having no time. It is on the contrary born of a vague fear that we are wasting our life. When we do not do the one thing we ought to do, we have no time for anything else—we are the busiest people in the world.”
—Eric Hoffer (1902–1983)
