This is a line from Terence’s Latin comedy Heauton Timorumenos (The Self-Tormentor, 163 BC), Act IV, scene 6. The young man Clitipho says it: Nullast tam facili’ res quin difficilis siet, quam invitu’ facias. The popular English follows H. T. Riley’s prose translation, which ends “…when you do it with reluctance.” No source ties it to Pythagoras.

There is nothing so easy but that it becomes difficult when you do it with reluctance. As this walk of mine, for instance, though not fatiguing, it has reduced me to weariness.
Act IV, scene 6
Riley’s translation. The Latin reads Nullast tam facili’ res quin difficilis siet, / quam invitu’ facias. The popular version changes Riley’s “with reluctance” to “reluctantly.” John Sargeaunt’s 1912 Loeb translation instead has “when you do it against the grain.”

Why Pythagoras gets the credit
Quote sites often put this line under Pythagoras. It is a short, wise-sounding maxim, the kind that collects around a famous ancient name. It comes from a Roman comedy written about three centuries after Pythagoras.

Context
The scene behind the saying
In the play, the line is a complaint, not advice. Clitipho, son of Chremes, is in love with the courtesan Bacchis. He has been sent off on a walk he did not want to take, and he grumbles to himself that even an easy errand is hard when you do it unwillingly. Riley’s translation goes on: “As this walk of mine, for instance, though not fatiguing, it has reduced me to weariness.”
Lifted out of the scene, the remark reads like a general maxim, and as a maxim it was later pinned on Pythagoras.
Nullast tam facili’ res quin difficilis siet, quam invitu’ facias.

Publius Terentius Afer was a Roman writer of comedies. Ancient authors say he was born in Carthage and brought to Rome as a slave, where he was educated and later freed. The Self-Tormentor (163 BC) is one of his six surviving plays. Like most of them, it was adapted from a Greek comedy by Menander.
