Famous quotes containing the word failures:

    “I have never worked for fame or praise, and shall not feel their loss as I otherwise would. I have never for a moment lost sight of the humble life I was born to, its small environments, and the consequently little right I had to expect much of myself, and shall have the less to censure, or upbraid myself with for the failures I must see myself make.”
    —Clara Barton (1821–1912)
