I saddens me greatly that there are people in this world who have read self help books, or spiritual types of books, and not read The Hitchhikers Guide to the Galaxy. Everyone knows that H2G2 has the biggest self help gyaan in the galaxy - 'Don't Panic' (in large, friendly letters, no less). What greater spiritual meaning can there be than 42, the answer to life, the universe and everything?
If you are a member of this group of people, please, please, remedy the situation by reading H2G2 as soon as possible. It's the best self help you could possibly get!
