Famous quotes containing the words optimal and/or rulers:
“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)
“Of the best rulers The people only know that they exist; The next best they love and praise The next they fear; And the next they revile. When they do not command the people’s faith, Some will lose faith in them, And then they resort to oaths! But of the best when their task is accomplished, their work done, The people all remark, “We have done it ourselves.””
—Lao-Tzu (6th century B.C.)
