Letter 31 — On Siren Songs (§3)

“What they wish to have heaped upon you are not really good things; there is only one good, the cause and the support of a happy life,—trust in oneself. But this cannot be attained, unless one has learned to despise toil and to reckon it among the things which are neither good nor bad. For it is not possible that a single thing should be bad at one time and good at another, at times light and to be endured, and at times a cause of dread.”
