Saadi said this quote

Have patience. All things are difficult before they become easy.

~ Saadi

Roam abroad in the world, and take thy fill of its enjoyments before the day shall come when thou must quit it for good.

~ Saadi

However much you study, you cannot know without action. A donkey laden with books is neither an intellectual nor a wise man. Empty of essence, what learning has he whether upon him is firewood or book?

~ Saadi

People are crying up the rich and variegated plumage of the peacock, and he is himself blushing at the sight of his ugly feet.
