I read about 5 books a month. Math books: always worth reading. Programming books: never worth reading. Fiction: a pleasant way to spend time, but rarely pays off. History: mostly crap, but personal memoirs are often insightful. Books that changed me: Orwell's "1984" (role of words), Hunter Thompson (personal courage), Henry Ford's "My Life and Work" (work attitude). Good stuff that should be better known: Eric Hoffer's "True Believer", Jerome K. Jerome's "Idle Thoughts of an Idle Fellow", Marcus Aurelius.
