Famous quotes containing the word problems:
“The problems of victory are more agreeable than the problems of defeat, but they are no less difficult.”
—Winston Churchill (1874–1965)
“I was a wonderful parent before I had children. I was an expert on why everyone else was having problems with theirs. Then I had three of my own.”
—Adele Faber (20th century)
“The problems of society will also be the problems of the predominant language of that society. It is the carrier of its perceptions, its attitudes, and its goals, for through it, the speakers absorb entrenched attitudes. The guilt of English then must be recognized and appreciated before its continued use can be advocated.”
—Njabulo Ndebele (b. 1948)
