Famous quotes containing the word growth:
“Interpretation is the evidence of growth and knowledge, the latter through sorrow— that great teacher.”
—Eleonora Duse (1858–1924)
“But parents can be understanding and accept the more difficult stages as necessary times of growth for the child. Parents can appreciate the fact that these phases are not easy for the child to live through either; rapid growth times are hard on a child. Perhaps it’s a small comfort to know that the harder-to-live-with stages do alternate with the calmer times,so parents can count on getting periodic breaks.”
—Saf Lerman (20th century)
“Perhaps our national ambition to standardize ourselves has behind it the notion that democracy means standardization. But standardization is the surest way to destroy the initiative, to benumb the creative impulse above all else essential to the vitality and growth of democratic ideals.”
—Ida M. Tarbell (1857–1944)
