Famous quotes containing the words television and/or work:
“Laughter on American television has taken the place of the chorus in Greek tragedy.... In other countries, the business of laughing is left to the viewers. Here, their laughter is put on the screen, integrated into the show. It is the screen that is laughing and having a good time. You are simply left alone with your consternation.”
—Jean Baudrillard (b. 1929)
“You say that you do not succeed much. Does it concern you enough that you do not? Do you work hard enough at it? Do you get the benefit of discipline out of it? If so persevere. Is it a more serious thing than to walk a thousand miles in a thousand successive hours? Do you get any corns by it? Do you ever think of hanging yourself on account of failure?”
—Henry David Thoreau (1817–1862)
