Letters 31.7

“But,” you say, “is not trifling and superfluous work, and work that has been inspired by ignoble causes, a bad sort of work?” No; no more than that which is expended upon noble endeavours, since the very quality that endures toil and rouses itself to hard and uphill effort, is of the spirit, which says: “Why do you grow slack? It is not the part of a man to fear sweat.”

Seneca, Letters to Lucilius 31.7, translated by Richard Mott Gummere
