In the solitude of the work — the work of art, the literary work — we discover a more essential solitude. It excludes the complacent isolation of individualism; it has nothing to do with the quest for singularity. The fact that one sustains a stalwart attitude throughout the disciplined course of the day does not dissipate it. He who writes the work is set aside; he who has written it is dismissed. He who is dismissed, moreover, doesn’t know it. This ignorance preserves him. It distracts him by authorizing him to persevere. The writer never knows whether the work is done. What he has finished in one book, he starts over or destroys in another.
— Blanchot, The Essential Solitude (quoted here)
