Alice in Wonderland: 
"But then, shall I never get any older than I am now? That'll be a comfort, one way -- never to be an old woman -- but then -- always to have lessons to learn!" 
"Why is a raven like a writing desk?"  
"It was much pleasanter at home, when one wasn't always growing larger and smaller, and being ordered about by mice and rabbits."  
Hitchhiker's Guide to the Galaxy: 
"This planet has  or rather had  a problem, which was this: most of the people living on it were unhappy for pretty much all of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn't the small green pieces of paper that were unhappy." 
Jane Eyre: 
"I am no bird; and no net ensnares me: I am a free human being with an independent will, which I now exert to leave you."
Earth, I think?
