Famous quotes containing the words missing and/or data:
“Teenage girls are extremists who see the world in black-and- white terms, missing shades of gray. Life is either marvelous or not worth living. School is either pure torment or is going fantastically. Other people are either great or horrible, and they themselves are wonderful or pathetic failures. One day a girl will refer to herself as the goddess of social life and the next day shell regret that shes the ultimate in nerdosity.”
—Mary Pipher (20th century)
“Mental health data from the 1950s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isnt surprising. If society tells you that your main role is to be attractive to men and you are getting crows feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
