Famous quotes containing the word work:
“I knew that my vocation was found. I had received the call, and having done so, I was sure my work would be assigned me. Of some things we feel quite certain. Inside there is a click, a kind of bell that strikes, when the hands of our destiny meet at the meridian hour.”
—Amelia E. Barr (1831–1919)
