Famous quotes containing the word ranks:
“Do not try to push your way through to the front ranks of your profession; do not run after distinctions and rewards; but do your utmost to find an entry into the world of beauty.”
—Konstantin Stanislavsky (1863–1938)
“Every woman who vacates a place in the teachers’ ranks and enters an unusual line of work, does two excellent things: she makes room for someone waiting for a place and helps to open a new vocation for herself and other women.”
—Frances E. Willard (1839–1898)
