“Life's a forge! Yes, and hammer and anvil, too! You'll be roasted, smelted, and pounded, and you'll scarce know what's happening to you. But stand boldly to it! Metal's worthless till it's shaped and tempered! More labor than luck. Face the pounding, don't fear the proving; and you'll stand well against any hammer and anvil.”
― Lloyd Alexander, Taran Wanderer

“You thought, as a boy, that a mage is one who can do anything. So I thought, once. So did we all. And the truth is that as a man's real power grows and his knowledge widens, ever the way he can follow grows narrower: until at last he chooses nothing, but does only and wholly what he must do. . . .”
― Ursula K. Le Guin, A Wizard of Earthsea

“When I was young, I had to choose between the life of being and the life of doing. And I leapt at the latter like a trout to a fly. But each deed you do, each act, binds you to itself and to its consequences, and makes you act again and yet again. Then very seldom do you come upon a space, a time like this, between act and act, when you may stop and simply be. Or wonder who, after all, you are.”
― Ursula K. Le Guin, The Farthest Shore

“As you read a book word by word and page by page, you participate in its creation, just as a cellist playing a Bach suite participates, note by note, in the creation, the coming-to-be, the existence, of the music. And, as you read and re-read, the book of course participates in the creation of you, your thoughts and feelings, the size and temper of your soul.”
― Ursula K. Le Guin
