The Secret Garden by Frances Hodgson Burnett
In each century since the beginning of the world wonderful things have been discovered. In the last century more amazing things were found out than in any century before. In this new century hundreds of things still more astounding will be brought to light. At first people refuse to believe that a strange new thing can be done, then they begin to hope it can be done, then they see it can be done—then it is done and all the world wonders why it was not done centuries ago. One of the new things people began to find out in the last century was that thoughts—just mere thoughts—are as powerful as electric batteries—as good for one as sunlight is, or as bad for one as poison. To let a sad thought or a bad one get into your mind is as dangerous as letting a scarlet fever germ get into your body. If you let it stay there after it has got in you may never get over it as long as you live.
 The Twits by Roald Dahl
“If a person has ugly thoughts, it begins to show on the face. And when that person has ugly thoughts every day, every week, every year, the face gets uglier and uglier until you can hardly bear to look at it. A person who has good thoughts cannot ever be ugly. You can have a wonky nose and a crooked mouth and a double chin and stick-out teeth, but if you have good thoughts it will shine out of your face like sunbeams and you will always look lovely.”
 The Merchant of Venice by William Shakespeare
Shylock: To bait fish withal; if it will feed nothing else, it will feed my revenge. He hath disgraced me and hindered me half a million, laughed at my losses, mocked at my gains, scorned my nation, thwarted my bargains, cooled my friends, heated mine enemies – and what’s his reason? I am a Jew. Hath not a Jew eyes? Hath not a Jew hands, organs, dimensions, senses, affections, passions; fed with the same food, hurt with the same weapons, subject to the same diseases, healed by the same means, warmed and cooled by the same winter and summer as a Christian is? If you prick us, do we not bleed? If you tickle us, do we not laugh? If you poison us, do we not die? And if you wrong us, shall we not revenge? If we are like you in the rest, we will resemble you in that. If a Jew wrong a Christian, what is his humility? Revenge. If a Christian wrong a Jew, what should his sufferance be by Christian example? Why, revenge. The villainy you teach me, I will execute, and it shall go hard but I will better the instruction.
 Little Women by Louisa May Alcott
“Have regular hours for work and play; make each day both useful and pleasant, and prove that you understand the worth of time by employing it well. Then youth will bring few regrets, and life will become a beautiful success.”
 Harry Potter and the Sorcerer’s stone by J.K.Rowling
“Now, can you think what the Mirror of Erised shows us all?”
Harry shook his head.
“Let me explain.The happiest man on earth would be able to use the Mirror of Erised like a normal mirror, that is, he would look into it and see himself exactly as he is. Does that help?”
Harry thought. Then he said slowly, “It shows us what we want… whatever we want…”
“Yes and no,” said Dumbledore quietly.
“It shows us nothing more or less than the deepest, most desperate desire of our hearts. You, who have never known your family, see them standing around you. Ronald Weasley, who has always been overshadowed by his brothers, sees himself standing alone, the best of all of them. However, this mirror will give us neither knowledge nor truth. Men have wasted away before it, entranced by what they have seen, or been driven mad, not knowing if what it shows is real or even possible. The Mirror will be moved to a new home tomorrow, Harry, and I ask you not to go looking for it again. If you ever do run across it, you will now be prepared. It does not do to dwell on dreams and forget to live, remember that.”
 The battle of the Labyrinth by Rick Riordan
“But remember, boy, that a kind act can sometimes be as powerful as a sword. As a mortal, I was never a great fighter or athlete or poet. I only made wine. The people in my village laughed at me. They said I would never amount to anything. Look at me now. Sometimes small things can become very large indeed.”
 Jane Eyre by Charlotte Bronte
“It is in vain to say human beings ought to be satisfied with tranquillity: they must have action; and they will make it if they cannot find it. Millions are condemned to a stiller doom than mine, and millions are in silent revolt against their lot. Nobody knows how many rebellions besides political rebellions ferment in the masses of life which people earth. Women are supposed to be very calm generally: but women feel just as men feel; they need exercise for their faculties, and a field for their efforts, as much as their brothers do; they suffer from too rigid a restraint, to absolute a stagnation, precisely as men would suffer; and it is narrow-minded in their more privileged fellow-creatures to say that they ought to confine themselves to making puddings and knitting stockings, to playing on the piano and embroidering bags. It is thoughtless to condemn them, or laugh at them, if they seek to do more or learn more than custom has pronounced necessary for their sex.”
 The Chronicles of Narnia by C.S. Lewis
“Peter did not feel very brave; indeed, he felt he was going to be sick. But that made no difference to what he had to do.”
 Howl’s Moving Castle by Diana Wynne Jones
“So you were going to rescue the Prince! Why did you pretend to run away? To deceive the Witch?”
Not likely!” Howl yelled. “I’m a coward. Only way I can do something this frightening is to tell myself I’m not doing it!”
 Coraline by Neil Gaiman
“And he said that wasn’t brave of him, doing that, just standing there and being stung,” said Coraline to the cat. “It wasn’t brave because he wasn’t scared: it was the only thing he could do. But going back again to get his glasses, when he knew the wasps were there, when he was really scared. That was brave.”
She took her first step down the dark corridor.
She could smell dust and damp and mustiness.
The cat padded along beside her.
“And why was that?” asked the cat, although it sounded barely interested.
“Because,” she said, “when you’re scared but you still do it anyway, that’s brave.”
 Pride and Prejudice by Jane Austin
“I have been a selfish being all my life, in practice, though not in principle. As a child I was taught what was right, but I was not taught to correct my temper. I was given good principles, but left to follow them in pride and conceit. Unfortunately an only son (for many years an only child), I was spoilt by my parents, who, though good themselves (my father, particularly, all that was benevolent and amiable), allowed, encouraged, almost taught me to be selfish and overbearing; to care for none beyond my own family circle; to think meanly of all the rest of the world; to wish at least to think meanly of their sense and worth compared with my own. Such I was, from eight to eight and twenty; and such I might still have been but for you, dearest, loveliest Elizabeth! What do I not owe you! You taught me a lesson, hard indeed at first, but most advantageous. By you, I was properly humbled. I came to you without a doubt of my reception. You showed me how insufficient were all my pretensions to please a woman worthy of being pleased.”
 My Sister’s Keeper by Jodi Picoult
“You don’t love someone because they’re perfect, you love them in spite of the fact that they’re not.”
 The Mysterious Island by Jules Verne
“So is man’s heart. The desire to perform a work which will endure, which will survive him, is the origin of his superiority over all other living creatures here below. It is this which has established his dominion, and this it is which justifies it, over all the world.”
 War of the Worlds by H.G. Wells
“We must remember what ruthless and utter destruction our own species has wrought, not only upon animals, such as vanished bison and the dodo, but upon its own inferior races. The Tasmanians were entirely swept out of existence in a war of extermination waged by European immigrants, in the space if fifty years. Are we such apostles of mercy as to complain if the Martians warred in the same spirit?”
 A Tale of Two Cities by Charles Dickens
“It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us, we had nothing before us, we were all going direct to Heaven, we were all going direct the other way.”
