Fr. John Lopez Agundez preaches about hope as the source of optimism: There's no optimism without hope. The hopeful man realizes he is a pilgrim walking to heaven; he does not look back, he looks forward. Josemaria saw the DYA academy bombed out during the Spanish Civil War, but shortly after that setback, he preached to the others about optimism. He was still hopeful and transmitted this to others around.
