【简答题】
A life of slothful ease, a life of that peace which springs merely from lack either of desire or of power to strive after great things, is as little worthy of a nation as an individual. We do not admire the man of timid peace. We admire the man who embodies victorious efforts, the man who never wrongs his neighbor, 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. Freedom from effort in the present merely means that there has been effort stored up in the past. A man can be freed from the necessity of work only by the fact that he or his fathers before him have worked to good purpose. If the freedom thus purchased is used aright, and the man still does actual work, though of a different kind, whether as a writer or a general, whether in the field of politics or in the field of exploration and adventure, he shows he deserves his good fortune.
