"That 99% of compulsive thinkers' thinking is about themselves; that 99% of this self-directed thinking consists of imagining and then getting ready for things that are going to happen to them; and then, weirdly, that if they stop to think about it, that 100% of the things they spend 99% of their time and energy imagining and trying to prepare for all the contingencies and consequences of are never good... In short that 99% of the head's thinking activity consists of trying to scare the everliving shit out of itself."

-David Foster Wallace, Infinite Jest
