Famous quotes containing the words hard and/or start:
“Some are “industrious,” and appear to love labor for its own sake, or perhaps because it keeps them out of worse mischief; to such I have at present nothing to say. Those who would not know what to do with more leisure than they now enjoy, I might advise to work twice as hard as they do,—work till they pay for themselves, and get their free papers.”
—Henry David Thoreau (1817–1862)
“When you’re 50 you start thinking about things you haven’t thought about before. I used to think getting old was about vanity—but actually it’s about losing people you love. Getting wrinkles is trivial.”
—Joyce Carol Oates (b. 1938)
