Famous quotes containing the word problems:
“If family communication is good, parents can pick up the signs of stress in children and talk about it before it results in some crisis. If family communication is bad, not only will parents be insensitive to potential crises, but the poor communication will contribute to problems in the family.”
—Donald C. Medeiros (20th century)
“There are nowadays professors of philosophy, but not philosophers. Yet it is admirable to profess because it was once admirable to live. To be a philosopher is not merely to have subtle thoughts, nor even to found a school, but so to love wisdom as to live according to its dictates, a life of simplicity, independence, magnanimity, and trust. It is to solve some of the problems of life, not only theoretically, but practically.”
—Henry David Thoreau (1817–1862)
“There is an enormous chasm between the relatively rich and powerful people who make decisions in government, business, and finance and our poorer neighbors who must depend on these decisions to alleviate the problems caused by their lack of power and influence.”
—Jimmy Carter (James Earl Carter, Jr.)
