It really has the best advice. obviously.
  1. The universe is a confusing place, therefore the world is a confusing place and your place in the world with it. Thinking on it too hard will only result in headaches.
    "The chances of finding out what's really going on in the universe are so remote, the only thing to do is hang the sense of it and keep yourself occupied.
  2. Marvin the Paranoid Android is all of us. Our insecurities buried deep down inside that sometimes come to the surface in the voice of Alan Rickman.
    "It's part of the shape of the Universe. I only have to talk to somebody and they begin to hate me."
  3. Always be prepared for change. And always bring a towel.
    "A towel, it says, is about the most massively useful thing an interstellar hitchhiker can have. Partly it has great practical value. You can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapors; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon... and of course dry yourself off with it if it still seems clean enough."
  4. We're always asking the wrong questions.
    "Forty-two! Is that all you've got to show for seven and a half million years' work?" "I checked it quite thoroughly," said the computer, "and that quite definitely is the answer. I think the problem, to be quite honest with you, is that you've never actually known what the question is. "
  5. A healthy dose of skepticism never hurt anybody, just don't expect the world to suddenly make sense.
    "We demand rigidly defined areas of doubt and uncertainty!"
  6. That everyone really needs to read it if they haven't and if they have its probably high time to read it again
  7. Don't panic.
    "Don't panic."
