Infinite Power for Richer Living

A cross between Napoleon Hill and Norman Vincent Peale, with a metaphysical twist, Joseph Murphy gives the reader an early self help book which is loaded with the benefits of positive thinking, right affirmation and prayer. He also dabbles a bit in the metaphysical, discussing intuitive faculties and the use of clairvoyants and mediums.
This book stresses that whatever you think about will grow... so don't discuss your aches and pains, worries, etc. It also discusses "the guiding principle" and how listening to it (your inner guidance) and following it's message will allow you to receive all the help you need to live successfully.
