If you look at the library of most millionares you will find a variety of books, some unique to that person and others that seem to be read by all of these people. One of the books that seems to be commonly mentioned by high achievers and millioinares as having been very influencial to them is Napolean Hill's Think and Grow Rich. The original book was published in 1936 and thus is no longer covered under copywrite laws. Various publishers have taken the original and added something too it, thus giving themselves a product that can be protected by copywrite law, but the original is not. If anyone is interested in downloading Hill's book in PDF format it is available on Google books.
