I have several favorites for different reasons. With my current mind frame, I’m into:
Networking with Millionaires, by Thomas J. Stanley
Helps to know how to focus on helping others so that assistance will come your way. I look at it as business karma.
The Secret, by Rhonda Byrne
Helps you to understand how you can will something into existence. Powers of attraction.
The 4-Hour Workweek, by Timothy Ferriss
Helps to see various exits from a 9 to 5. Also provides tips on maximizing your time.
The Cash Flow Quadrant, by Robert T. Kiyosaki, Sharon L. Lechter
Helps you to see where you are and have an understanding of where you’d like to be in the Employee, Self-Employed, Business Owner or Investor relms (quadrants).
Multiple Streams of Income, by Robert G. Allen
Helps you to understand that the best way to achieve a financial goal is by not putting all your eggs in one basket (strategy).
The above are just a few.
