“The quest of the Inner Ring will break your hearts unless you break it. But if you break it, a surprising result will follow. If in your working hours you make the work your end, you will presently find yourself all unawares inside the only circle in your profession that really matters. You will be one of the sound craftsmen, and other sound craftsmen will know it. This group of craftsmen will by no means coincide with the Inner Ring or the Important People or the People in the Know. It will not shape that professional policy or work up that professional influence which fights for the profession as a whole against the public: nor will it lead to those periodic scandals and crises which the Inner Ring produces. But it will do those things which that profession exists to do and will in the long run be responsible for all the respect which that profession in fact enjoys and which the speeches and advertisements cannot maintain. And if in your spare time you consort simply with the people you like, you will again find that you have come unawares to a real inside: that you are indeed snug and safe at the center of something which, seen from without, would look exactly like an Inner Ring. But the difference is that its secrecy is accidental, and its exclusiveness a by-product, and no one was led thither by the lure of the esoteric: for it is only four or five people who like one another meeting to do things that they like. This is friendship. Aristotle placed it among the virtues. It causes perhaps half of all the happiness in the world, and no Inner Ring can ever have it.”

“Il nostro giocare in piccolo non serve al mondo.”

“La vida no está libre de problemas, y nunca lo estará. Solamente encontrarás a un grupo de personas que están libres de problemas, y tienes que ir al cementerio de tu ciudad para encontrarlas. Mientras tengamos aliento, vamos a tener épocas de abundancia y épocas en que luchemos, épocas en que las circunstancias sean buenas y otras en que sean malas. Que las circunstancias hagan lo que quieran; en cuanto a ti, decide permanecer estable.”

“Don’t answer every critic. Sometimes, the answers you give may be right but misconceived and misunderstood.”
