A man can stand a lot as long as he can stand himself. He can live without hope, without friends, without books, even without music, as long as he can listen to his own thoughts.
Nothing is so contagious as enthusiasm; it moves stones, it charms brutes. Enthusiasm is the genius of sincerity, and truth accomplishes no victories without it.
Shall you complain who feed the world? Who clothe the world? Who house the world? Shall you complain who are the world, Of what the world may do? As from this hour You use your power, The world must follow you!
