From Proverbs and Tiny Songs

You walking, your footsteps are the road, and nothing else; there is no road, walker, you make the road by walking. By walking you make the road, and when you look backward, you see the path that you never will step on again. Walker, there is no road, Only wind-trails in the sea.

– By Antonio Machado (1875–1939), translated by Robert Bly
