Have no friends not equal to yourself.
I transmit but do not create. I place my trust in the teachings of antiquity.
In vain I have looked for a single man capable of seeing his own faults and bringing the charge home against himself.
A ruthless man extends his ruthlessness from those he does not love to those he loves.
Reviewing what you have learned and learning anew, you are fit to be a teacher.
A hammer shatters glass but it also forges steel.
