Always give a word or sign of salute when meeting or passing a friend, or even a stranger, if in a lonely place.

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.

Every man must do two things alone he must do his own believing and his own dying.

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.

Unless we love and are loved, each of us is alone, each of us is deeply lonely.
