His boss, a gruff man named Mr. Harriman, read it and tossed it back. “Pretty words, Leo. But will it sell?” Tested Advertising Methods John Caples .pdf

So whether you have that PDF open right now or not, remember: the market is the only judge that matters. Test everything. Trust nothing. And never, ever write a headline you haven’t put to the vote of a split-run.
