Famous quotes containing the word personal:
“A man who has nothing which he cares about more than he does about his personal safety is a miserable creature who has no chance of being free, unless made and kept so by the existing of better men than himself.”
—John Stuart Mill (1806–1873)
“The grief of the keen is no personal complaint for the death of one woman over eighty years, but seems to contain the whole passionate rage that lurks somewhere in every native of the island. In this cry of pain the inner consciousness of the people seems to lay itself bare for an instant, and to reveal the mood of beings who feel their isolation in the face of a universe that wars on them with winds and seas.”
—J.M. (John Millington)
“I leave the governor’s office next week, and with it public life ... [which] has been on the whole a pleasant one. But for ten years and over my salaries have not equalled my expenses, and there has been a feeling of responsibility, a lack of independence, and a necessary neglect of my family and personal interests and comfort, which make the prospect of a change comfortable to think of.”
—Rutherford Birchard Hayes (1822–1893)
