Antonio Muchado y Ruiz, one of the Spanish poets of the famous "Generation of 1898" wrote a beautiful poem about one making the road as one travels...

Caminante
Caminante, son tus huellas
el camino, y nada mas;
Caminante, no hay camino;
se hace el camino al andar.
Al andar se hace camino
Y al volver la vista atras
se ve la senda que nunca
se ha de volver a pisar.
Caminante, no hay camino,
si no estelas en la mar.

Traveller
Traveller, your footprints are
the road and nothing more.
Traveller, there is no raod;
the road is made as you travel.
Travelling, the road is made,
and as you turn to look back
you can see the path that
shall not be wallked on again.
Traveller, there is no road,
only a trail in the sea.
