Seneca · On business as the enemy of philosophy

Letters 72.2

For there are certain subjects about which you can write even while travelling in a gig, and there are also subjects which need a study-chair, and quiet, and seclusion. Nevertheless I ought to accomplish something even on days like these,—days which are fully employed, and indeed from morning till night. For there is never a moment when fresh employments will not come along; we sow them, and for this reason several spring up from one. Then, too, we keep adjourning our own cases, saying: “As soon as I am done with this, I shall settle down to hard work,” or: “If I ever set this troublesome matter in order, I shall devote myself to study.”

Seneca, Letters to Lucilius 72.2, translated by Richard Mott Gummere
