Famous quotes containing the word prime:
“One wants in a Prime Minister a good many things, but not very great things. He should be clever but need not be a genius; he should be conscientious but by no means strait-laced; he should be cautious but never timid, bold but never venturesome; he should have a good digestion, genial manners, and, above all, a thick skin.”
—Anthony Trollope (1815–1882)
“Being prime minister is a lonely job.... you cannot lead from the crowd.”
—Margaret Thatcher (b. 1925)
“And shall I prime my children, pray, to pray?”
—Gwendolyn Brooks (b. 1917)
