One of my favorite passages from Infinite Jest, although it doesn't begin to do justice to the book as a whole

“That you do not have to like a person in order to learn from him/her/it.  That loneliness is not a function of solitude.  That it is possible to get so angry you really do see everything red.  What a ‘Texas Catheter’ is.  That some people really do steal –– and will steal things that are yours.  That a lot of U.S. adults truly cannot read, not even a ROM hypertext phonics thing with HELP functions for every word.  That cliquey alliance and exclusion and gossip can be forms of escape.  That logical validity is not a guarantee of truth.  That evil people never believe they are evil, but rather that everyone else is evil.  That it is possible to learn valuable things from a stupid person.  That it takes effort to pay attention to any one stimulus for more than a few seconds.  That you can all of a sudden out of nowhere want to get high with your Substance so bad that you think you will surely die if you don’t, and but can just sit there with your hands writhing in your lap and face wet with craving, can want to get high but instead just sit there, wanting to but not, if that makes sense, and if you can gut it out and not hit the Substance during the craving the craving will eventually pass, it will go away –– at least for a while.  That it is statistically easier for low-IQ people to kick an addiction than it is for high-IQ people.  That the metro Boston street term for panhandling is: stemming, and that it is regarded by some as a craft or art; and that professional stem-artists actually have like little professional colloquia sometimes, little conventions, in parks or public-transport hubs, at night, where they get together and network and exchange feedback on trends and techniques and public relations, etc.  That is possible to abuse OTC cold-and allergy remedies in an addictive manner.  That Nyquil is over 50 proof.  That boring activities become, perversely, much less boring if you concentrate intently on them.  That if enough people in a silent room are drinking coffee it is possible to make out the sound of steam coming off the coffee.  That sometimes human beings have to just sit in one place and, like, hurt.  That you will become way less concerned with what other people think of you when you realize how seldom they do.  That there is such a thing as raw, unalloyed, agendaless kindness.  That it is possible to fall asleep during an anxiety attack.”
