Best book on the knack for getting money is "How to Get Rich" by Felix Dennis, founder of Maxim magazine (worth between $400-900M, that's what he says in the book): http://www.amazon.com/How-Get-Rich-Greatest-Entrepreneurs/dp...

Here's a good Inc. article on it too: http://www.inc.com/articles/2008/07/dennis.html

Utter determination, fearlessness, tunnel vision, and hard work are his answers.
