Another one that I highly recommend other than "Think and Grow Rich" by Napoleon Hill that I forgot to mention is "ASK AND IT IS GIVEN" by Esther & Jerry Hicks. It's similar to the best seller "The Law of Attraction" but this one has step by step process you can immediately follow steps within your most immediate interest. This is more spiritual approach for business and personal success and manifestation.
I have both books listed on my blog as well.
