One of the best that I know is the Millionaire Mind Intensive Seminar from Peak Potentials: http://www.millionairemind.com/a/?wid=587389&page=/preview/replay
The seminar is based on the T. Harv Eker’s book, Secrets of the Millionaire Mind: http://www.amazon.com/exec/obidos/ASIN/0060763280/curtissanaemarti/ The basic idea is that the way that you think and feel about money determines your success or failure.

Another favorite of mine is the Rich Dad site: http://www.myaffiliateprogram.com/u/connect/t.asp?id=19516
Robert Kiyosaki has a great series of books that explain his “Rich Dad, Poor Dad” philosophy. He has also developed “Ca$hFlow” a very popular board game that teaches personal finance while playing the game. There are Ca$hFlow gaming clubs all over the country where people get together to play the game and network.

Another classic is the Science of Getting Rich, by Wallace D. Wattles. This also focuses on the way you think. Positive attitude and gratitude goes a long way toward making you successful. This is the book that jump-started “The Secret” phenomenon. You can get a free copy of the e-book at this site: http://www.1shoppingcart.com/app/?af=590851

Another comprehensive site is The Motley Fool page: http://www.fool.com/pf.htm?source=ifltnvpnv0000001 Lots of good information here.
