The Art of Worldly Wisdom (Ducool Authoritative Genuine Edition)

Baltasar Gracián studied thoroughly on human characters and personalities. If you want to be respected, don't let anyone know about you and keep yourself in a secret situation. Don't exhaust yourself at the beginning, you should do better and better and make your rivals scared. You should cautiously foresee the troubles and cautiously solve them. Don't be too kind to let others do evil things. You should be half devil and half angel.
