Letters 74.1

Your letter has given me pleasure, and has roused me from sluggishness. It has also prompted my memory, which has been for some time slack and nerveless.

You are right, of course, my dear Lucilius, in deeming the chief means of attaining the happy life to consist in the belief that the only good lies in that which is honourable. For anyone who deems other things to be good, puts himself in the power of Fortune, and goes under the control of another; but he who has in every case defined the good by the honourable, is happy with an inward happiness.

Seneca, Letters to Lucilius 74.1, translated by Richard Mott Gummere
