“We cannot all be masters, nor all masters cannot be truly follow’d. You shall mark many a duteous and knee-crooking knave that, doting on his own obsequious bondage, wears out his time, much like his master’s ass, for naught but provender; and when he’s old, cashier’d: whip me such honest knaves. Others there are who, trimm’d in forms and visages of duty, keep yet their hearts attending on themselves; and, throwing but shows of service on their lords, do well thrive by them, and when they have lin’d their coats, do themselves homage: these fellows have some soul.” – William Shakespeare, Othello, the Moor of Venice 1.1
