Bid a singer in a chorus, Know Thyself; and will he not turn for the knowledge to the others, his fellows in the chorus, and to his harmony with them?

Liars are the cause of all the sins and crimes in the world.

Be not swept off your feet by the vividness of the impression, but say, "Impression, wait for me a little. Let me see what you are and what you represent. Let me try you."

No man is free who is not master of himself... Is freedom anything else than the power of living as we choose?

What really frightens and dismays us is not external events themselves, but the way in which we think about them. It is not things that disturb us, but our interpretation of their significance.

Nothing truly stops you. Nothing truly holds you back. For your own will is always within your control. Sickness may challenge your body. But are you merely your body? Lameness may impede your legs. But you are not merely your legs. Your will is bigger than your legs. Your will needn't be affected by an incident unless you let it.

We can't control the impressions others form about us, and the effort to do so only debases our character.
