“Keep the extent of your abilities unknown.The wise man does not allow his knowledge and abilities to be sounded to the bottom, if he desires to be honored at all. He allows you to know them but not to comprehend them. No one must know the extent of his abilities, lest he be disappointed. No one ever has an opportunity of fathoming him entirely. For guesses and doubts about the extent of his talents arouse more veneration than accurate knowledge of them, be they ever so great.”
― Baltasar Gracián, The Art of Worldly Wisdom: A Pocket Oracle

“Humour is meant, in a literal sense, to make game of man; that is, to dethrone him from his official dignity and hunt him like game.”

“Without courage, wisdom bears no fruit.”
― Baltasar Gracian

“Never put off till tomorrow what may be done day after tomorrow just as well.”
