Archilochus

“We don't rise to the level of our expectations, we fall to the level of our training.”

“Heart, my heart, so battered with misfortune far beyond your strength, up, and face the men who hate us. Bare your chest to the assault of the enemy, and fight them off. Stand fast among the beamlike spears. Give no ground; and if you beat them, do not brag in open show, nor, if they beat you, run home and lie down on your bed and cry. Keep some measure in the joy you take in luck, and the degree you give away to sorrow. All your life is up-and-down like this.”

“The fox knows many tricks; the hedgehog one good one.”

“The fox has many tricks. The hedgehog has but one, but that is the best of all.”

“The fox knows many things, but the hedgehog knows one big thing.”
