Moral Letters to Lucilius Section 8

Maximum vitae vitium est, quod inperfecta semper est, quod aliquid ex illa differtur. Qui cotidie vitae suae summam manum inposuit, non indiget tempore. Ex hac autem indigentia timor nascitur et cupiditas futuri exedens animum. Nihil est miserius dubitatione venientium quorsus evadant; quantum sit illud quod restat aut quale, sollicita mens inexplicabili formidine agitatur.

Car elle pèche surtout en ceci que, toujours inachevée, on l’ajourne d’un temps à un autre. Qui sut chaque jour mettre à sa vie la dernière main n’est point à court de temps. Or de ce manque de temps naissent l’anxiété et la soif d’avenir qui ronge l’âme. Rien de plus misérable que ce doute : les événements qui approchent, quelle issue auront-ils ? Combien me reste-t-il de vie, et quelle sorte de vie ? Voilà ce qui agite de terreurs sans fin l’âme qui ne se recueillit jamais.

The greatest flaw in life is that it is always imperfect, and that a certain part of it is postponed. One who daily puts the finishing touches to his life is never in want of time. And yet, from this want arise fear and a craving for the future which eats away the mind. There is nothing more wretched than worry over the outcome of future events; as to the amount or the nature of that which remains, our troubled minds are set a-flutter with unaccountable fear.
