Ubik ... Safe when taken as directed. - Philip K. Dick

It isn't a brute instinct that keeps us restless and dissatisfied. I'll tell you what it is: it's the highest goal of man - the need to grow and advance . . . to find new things . . . to expand. To spread out, reach areas, experiences, comprehend and live in an evolving fashion. To push aside routine and repetition, to break out of mindless monotony and thrust forward. To keep moving on . . .

The hell with the newspapers. Nobody reads the letters to the editor column except the nuts. It's enough to get you down.

No man is infinitely strong; for every creature that runs, flies, hops or crawls there is a terminal nemesis which he will not circumvent, which will finally do him in.
