Famous quotes containing the word work:
“...I knew I wanted to be permanently self-supporting and I vaguely thought I might work somewhere in the realm of ideas. I felt that I had within me an undeveloped fount of ideas. I did not know exactly what my ideas were, but whatever they were I wanted to convert people to them.”
—Rheta Childe Dorr (1866–1948)
