Famous quotes containing the word advantages:
“There are great advantages to seeing yourself as an accident created by amateur parents as they practiced. You then have been left in an imperfect state and the rest is up to you. Only the most pitifully inept child requires perfection from parents.”
—Frank Pittman (20th century)
“To say that a man is your Friend, means commonly no more than this, that he is not your enemy. Most contemplate only what would be the accidental and trifling advantages of Friendship, as that the Friend can assist in time of need by his substance, or his influence, or his counsel.... Even the utmost goodwill and harmony and practical kindness are not sufficient for Friendship, for Friends do not live in harmony merely, as some say, but in melody.”
—Henry David Thoreau (1817–1862)
“[T]here is no Part of the World where Servants have those Privileges and Advantages as in England: They have no where else such plentiful Diet, large Wages, or indulgent Liberty: There is no place wherein they labour less, and yet where they are so little respectful, more wasteful, more negligent, or where they so frequently change their Masters.”
—Richard Steele (1672–1729)
