“In the most desirable conditions, the child learns to manage anxiety by being exposed to just the right amounts of it, not much more and not much less. This optimal amount of anxiety varies with the child’s age and temperament. It may also vary with cultural values.... There is no mathematical formula for calculating exact amounts of optimal anxiety. This is why child rearing is an art and not a science.”
—Alicia F. Lieberman (20th century)

“The only fruit which even much living yields seems to be often only some trivial success,—the ability to do some slight thing better. We make conquest only of husks and shells for the most part,—at least apparently,—but sometimes these are cinnamon and spices, you know.”
—Henry David Thoreau (1817–1862)
