Plutarch

"The wildest colts make the best horses."

"What we achieve inwardly will change outer reality."

"I don't need a friend who changes when I change and who nods when I nod my shadow does that much better."

"Courage consists not in hazarding without fear but being resolutely minded in a just cause."

"Courage stands halfway between cowardice and rashness, one of which is a lack, the other an excess of courage."

"The very spring and root of honesty and virtue lie in good education."
