'You know what your problem is, Hallie?' 'I have just one problem?' — David Foster Wallace

'So then at forty-six years of age I came here to learn to live by cliches,' is what Day says to Charlotte Treat right after Randy Lenz asked what time it was, again, at 0825. 'To turn my will and life over to the care of cliches. One day at a time. Easy does it. First things first. Courage is fear that has said its prayers. Ask for help. Thy will not mine be done. It works if you work it. Grow or go. Keep coming back.' [...] I walk around with my arms out straight in front of me and recite these cliches. In a monotone. No inflection necessary. Could that be one? Could that be added to the cliche-pool? "No inflection necessary"? Too many syllables, probably.'

That you will become way less concerned with what other people think of you when you realize how seldom they do.

The so-called ‘psychotically depressed’ person who tries to kill herself doesn't do so out of quote ‘hopelessness’ or any abstract conviction that life's assets and debits do not square. And surely not because death seems suddenly appealing. The person in whom Its invisible agony reaches a certain unendurable level will kill herself the same way a trapped person will eventually jump from the window of a burning high-rise. Make no mistake about people who leap from burning windows. Their terror of falling from a great height is still just as great as it would be for you or me standing speculatively at the same window just checking out the view; i.e. the fear of falling remains a constant. The variable here is the other terror, the fire's flames: when the flames get close enough, falling to death becomes the slightly less terrible of two terrors. It's not desiring the fall; it's terror of the flames. Yet nobody down on the sidewalk, looking up and yelling ‘Don‘t!’ and ‘Hang on!’, can understand the jump. Not really. You'd have to have personally been trapped and felt flames to really understand a terror way beyond falling.
