Baldassare Castiglione

“I have discovered a universal rule which seems to apply more than any other in all human actions or words: namely, to steer away from affectation at all costs, as if it were a rough and dangerous reef, and (to use perhaps a novel word for it) to practise in all things a certain nonchalance [sprezzatura] which conceals all artistry and makes whatever one says or does seem uncontrived and effortless.”
