Seneca · On the approaches to philosophy

Letters 108.37

A teacher like that can help me no more than a sea-sick pilot can be efficient in a storm. He must hold the tiller when the waves are tossing him; he must wrestle, as it were, with the sea; he must furl his sails when the storm rages; what good is a frightened and vomiting steersman to me? And how much greater, think you, is the storm of life than that which tosses any ship! One must steer, not talk.

All the words that these men utter and juggle before a listening crowd, belong to others.

Seneca, Letters to Lucilius 108.37, translated by Richard Mott Gummere
