If you want to win affection and respect in this world, you must flatter people.
 Jerome K. Jerome, Idle Thoughts of an Idle Fellow (1886). copy citation

Context

“from the dark-skinned African, bartering his rare oils and ivory for a few glass beads to hang about his neck, to the Christian maiden selling her white body for a score of tiny stones and an empty title to tack before her name—all march, and fight, and bleed, and die beneath its tawdry flag. Ay, ay, vanity is truly the motive-power that moves humanity, and it is flattery that greases the wheels. If you want to win affection and respect in this world, you must flatter people. Flatter high and low, and rich and poor, and silly and wise. You will get on famously. Praise this man's virtues and that man's vices. Compliment everybody upon everything, and especially upon what they haven't got.” source
