He who is really good can never be unhappy. He who is really wise can never be perplexed. He who is really brave is never afraid.

To know it is not as good as to love it, and to love it is not as good as to take delight in it.

A hammer shatters glass but it also forges steel.

A fool despises good counsel, but a wise man takes it to heart.

Not too isolated, not too many relationships, the middle, that's wisdom.

At 15 I set my heart on learning; At 30 I firmly took my stand; At 40 I had no delusions; At 50 I knew the Mandate of Heaven; At 60 my ear was attuned; At 70 I followed my heart's desire without overstepping the boundaries of right.

He Who Knows And Knows That He Knows Is A Wise Man - Follow Him; He Who Knows Not And Knows Not That He Knows Not Is A Fool - Shun Him
