“The road that stretches before the feet of a man is a challenge to his heart long before it tests the strength of his legs.
Our destiny is to run to the edge of the world and beyond, off into the darkness: certain despite all our blindness, secure despite all our helplessness, strong despite all our weakness, happily in love despite all the pressure on our hearts.“
from the Summa Theologica of St. Thomas Aquinas
