A number of writers use something as a stimulant. Is there anything that stimulates your writing? For example, a special room in your house?
I would simply say the light. The light of the day, of the sky. Light is a perceptible unity. When there is more light around you, you are more alert to the world’s situations, to its different aspects, to the mystery of time.
—Yves Bonnefoy, The Art of Poetry No. 69
