Variant translations:
A poem is never finished; it's always an accident that puts a stop to it — i.e. gives it to the public.
As attributed in Susan Ratcliffe, Concise Oxford Dictionary of Quotations (2011), p. 385.
A poem is never finished; it is only abandoned.
Widely quoted, this is a paraphrase of Valéry by W. H. Auden in 1965. See W. H. Auden: Collected Poems (2007), ed. Edward Mendelson, "Author's Forewords", p. xxx.
An artist never finishes a work, he merely abandons it.
A paraphrase by Aaron Copland in the essay "Creativity in America," published in Copland on Music (1944), p. 53
In the eyes of those lovers of perfection, a work is never finished — a word that for them has no sense — but abandoned; and this abandonment, whether to the flames or to the public (and which is the result of weariness or an obligation to deliver) is a kind of an accident to them, like the breaking off of a reflection, which fatigue, irritation, or something similar has made worthless.

Final lines, Ch. III : An afternoon party at the house of the Princesse de Guermantes"; translation by Stephen Hudson, Time Regained (1931)
If enough time was left to me to complete my work, my first concern would be to describe the people in it, even at the risk of making them seem colossal and unnatural creatures, as occupying a place far larger than the very limited one reserved for them in space, a place in fact almost infinitely extended, since they are in simultaneous contact, like giants immersed in the years, with such distant periods of their lives, between which so many days have taken up their place – in Time.
Translation by Ian Patterson, Finding Time Again (2002)
