Famous quotes containing the words optimal and/or play:
“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)
“This fellow is wise enough to play the fool,
And to do that well craves a kind of wit.
He must observe their mood on whom he jests,
The quality of persons, and the time,
Not, like the haggard, check at every feather
That comes before his eye. This is a practice
As full of labor as a wise man’s art.”
—William Shakespeare (1564–1616)
