A horse never runs so fast as when he has other horses to catch up and outpace.

The spirits run riot in youth.

Take this at least, this last advice, my son: Keep a stiff rein, and move but gently on: The coursers of themselves will run too fast, Your art must be to moderate their haste.

Lente, lente currite, noctis equi. Translation: Run slowly, slowly, horses of the night.
