“Hercules,” says she [Virtue], “I offer myself to you, because I know you are descended from the gods, and give proofs of that descent by your love to virtue, and application to the studies proper for your age. This makes me hope you will gain, both for yourself and me, an immortal reputation.
But, before I invite you into my society and friendship, I will be open and sincere with you, and must lay down this, as an established truth, that there is nothing truly valuable which can be purchased without pains and labor. The gods have set a price upon every real and noble pleasure.
If you would gain the favor of the Deity, you must be at the pains of worshiping him: if the friendship of good men, you must study to oblige them: if you would be honored by your country, you must take care to serve it. In short, if you would be eminent in war or peace, you must become master of all the qualifications that can make you so. These are the only terms and conditions upon which I can propose happiness.” – The Choice of Hercules, Xenophon
“I wish to preach, not the doctrine of ignoble ease, but the doctrine of the strenuous life, the life of toil and effort, of labor and strife; to preach that highest form of success which comes, not to the man of who desires more easy peace, but to the man who does not shrink from danger, from hardship, or from bitter toil, and who out of these wins the splendid ultimate triumph.”- Teddy Roosevelt
