Famous quotes containing the words dirty and/or data:
“Politics is still the man’s game. The women are allowed to do the chores, the dirty work, and now and then—but only occasionally—one is present at some secret conference or other. But it’s not the rule. They can go out and get the vote, if they can and will; they can collect money, they can be grateful for being permitted to work. But that is all.”
—Mary Roberts Rinehart (1876–1958)
“To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.”
—F. Scott Fitzgerald (1896–1940)
