Famous quotes containing the words early and/or models:
“Make-believe is the avenue to much of the young child’s early understanding. He sorts out impressions and tries out ideas that are foundational to his later realistic comprehension. This private world sometimes is a quiet, solitary
world. More often it is a noisy, busy, crowded place where language grows, and social skills develop, and where perseverance and attention-span expand.”
—James L. Hymes, Jr. (20th century)
“The parents who wish to lead a quiet life I would say: Tell your children that they are very naughty—much naughtier than most children; point to the young people of some acquaintances as models of perfection, and impress your own children with a deep sense of their own inferiority. You carry so many more guns than they do that they cannot fight you. This is called moral influence and it will enable you to bounce them as much as you please.”
—Samuel Butler (1835–1902)
