William Walker Atkinson,
The Psychology of Salesmanship
“ A blow that would knock the ordinary man off his pins will do nothing more than to give a professional boxer a chance to show his agility and win applause. If you drop a plank on a cork in the water with a tremendous splash the cork will bob up as serenely as if nothing had happened, and lie quietly once more on the unruffled surface of the water. And so a clever salesman, when a smashing blow is aimed at him by a surly prospect, will merely sidestep gracefully and continue calmly with the prosecution of his purpose. ”
