Letter 104 — On Care of Health and Peace of Mind (§22)

“Live with Chrysippus, with Posidonius: they will make you acquainted with things earthly and things heavenly; they will bid you work hard over something more than neat turns of language and phrases mouthed forth for the entertainment of listeners; they will bid you be stout of heart and rise superior to threats. The only harbour safe from the seething storms of this life is scorn of the future, a firm stand, a readiness to receive Fortune’s missiles full in the breast, neither skulking nor turning the back.”
