Napolean Hill was the author of "Think and Grow Rich" a very popular book, and I think that's self explanatory. I think he sold millions of copies and I know people who personally got a lot of motivation, particularly for business and sales, from reading his work. He passed away recently, and maybe this might be worth your time. Hold on: I just realized that Hill was a Christian of sorts and that this might be his Christian spin on positive thinking against negative "devil" thinking. So on second thought forget it.
