Letters 95.3

But I shall without pity avenge myself and shall load a huge letter upon your shoulders; for your part, if you read it with reluctance, you may say: “I brought this burden upon myself,” and may class yourself among those men whose too ambitious wives drive them frantic, or those whom riches harass, earned by extreme sweat of the brow, or those who are tortured with the titles which they have sought by every sort of device and toil, and all others who are responsible for their own misfortunes.

Seneca, Letters to Lucilius 95.3, translated by Richard Mott Gummere
