Your secret is your prisoner; once you reveal it, you become its slave.
Kings may be judges of the earth, but wise men are the judges of kings.
I am better able to retract what I did not say than what I did.
As long as a word remains unspoken, you are its master; once you utter it, you are its slave.
My friend is he who will tell me my faults in private.
Misfortune may become fortune through patience.
