Famous quotes containing the words performance and/or comparisons:
“The way to go to the circus, however, is with someone who has seen perhaps one theatrical performance before in his life and that in the High School hall.... The scales of sophistication are struck from your eyes and you see in the circus a gathering of men and women who are able to do things as a matter of course which you couldn’t do if your life depended on it.”
—Robert Benchley (1889–1945)
“The surest route to breeding jealousy is to compare. Since jealousy comes from feeling “less than” another, comparisons only fan the fires.”
—Dorothy Corkville Briggs (20th century)
