Famous quotes containing the words positive, negative and/or periods:
“I believe, as Maori people do, that children should have more adults in their lives than just their mothers and fathers. Children need more than one or two positive role models. It is in your children’s best interest that you help them cultivate a support system that extends beyond their immediate family.”
—Stephanie Marston (20th century)
“Mothers often are too easily intimidated by their children’s negative reactions...When the child cries or is unhappy, the mother reads this as meaning that she is a failure. This is why it is so important for a mother to know...that the process of growing up involves by definition things that her child is not going to like. Her job is not to create a bed of roses, but to help him learn how to pick his way through the thorns.”
—Elaine Heffner (20th century)
“Those who weep for the happy periods which they encounter in history acknowledge what they want; not the alleviation but the silencing of misery.”
—Albert Camus (1913–1960)
