Theodore Roosevelt began this 1899 speech with his thesis: "I wish to preach, not the doctrine of ignoble ease, but the doctrine of the strenuous life." He discusses how the many hardships of his life shaped him for the better. Roosevelt believed that if Americans wished to succeed in the world, they would need to embrace the virtue of hard work. He applied this same belief to foreign affairs, stating that America must establish itself as a powerful military force and exert this power when necessary.
