"what should you do to avoid being an idiot or a swine? Merely this: You should do something great, you should lay aside all the foolishness of a more of less long existence, you should become resigned to the fact that you will seem ridiculous to a race of janitors and bureaucrats if you are to enter the service of Splendor.
