Famous quotes containing the word work:
“Our kids will develop a work ethic only if we require them to pay a portion of the cost of some of the things they want. They’ll learn to defer gratification the moment we stop routinely pulling out our wallets. And they’ll learn self-discipline only if we care enough to enforce reasonable limits.”
—Fred G. Gosman (20th century)
