That's the title of a speech that Theodore Roosevelt gave in Chicago in 1899. Here is my favourite part:
We do not admire the man of timid peace. We admire the man who embodies victorious effort; the man who never wrongs his neighbour; who is prompt to help a friend; but who has those virile qualities necessary to win in the stern strife of actual life. It is hard to fail; but it is worse never to have tried to succeed. In this life we get nothing save by effort.
