And never grow a wishbone, daughter,
where your backbone ought to be.
Clementine Paddleford, “For My Daughter” 
You found the earth too great for your one life, you found your brain and sinew smaller than the hunger and desire that fed on them — but it has been this way with all men. You have stumbled on in darkness, you have been pulled in opposite directions, you have faltered, you have missed the way, but, child, this is the chronicle of the earth. And now, because you have known madness and despair, and because you will grow desperate again before you come to evening, we who have stormed the ramparts of the furious earth and been hurled back, we who have been maddened by the unknowable and bitter mystery of love, we who have hungered after fame and savored all of life, the tumult, pain, and frenzy, and now sit quietly by our windows watching all that henceforth never more shall touch us — we call upon you to take heart, for we can swear to you that these things pass.
Thomas Wolfe, You Can’t Go Home Again
Never expect to outgrow loneliness. Never hope to find people who will understand you, someone to fill that space. An intelligent, sensitive person is the exception, the very great exception. If you expect to find people who understand you, you will grow murderous with disappointment. The best you’ll ever do is to understand yourself, know what it is that you want, and not let the cattle stand in your way.
Janet Fitch, White Oleander
It’s no good trying to keep up old friendships. It’s painful for both sides. The fact is, one grows out of people, and the only thing is to face it.
W. Somerset Maugham, Cakes and Ale: Or, The Skeleton in the Cupboard
What greater wealth is there than to own your life and to spend it on growing? Every living thing must grow. It can’t stand still. It must grow or perish.
Ayn Rand, Atlas Shrugged
I want to keep walking away from the person I was a moment ago, because a mind was made fo figure things out, not to read the same page recurrently.
Donald Miller, Through Painted Deserts: Light, God, and Beauty on the Open Road
Prejudices, it is well known, are most difficult to eradicate from the heart whose soil has never been loosened or fertilised by education: they grow there, firm as weeds among stones.
Charlotte Brontë, Jane Eyre
