Kiyosaki divides cashflow into 4 (thus 'Quad') Quadrants or "sectors" (if you will) - employee, self-employed, business owner, and investor. Each of these groups or sectors are described in detail as to what type of cash each generates, how they generate the cashflow that they do, and why. Kiyosaki also details the difference between "job security" and "financial freedom," as it relates to cashflow, and each quadrant. Furthermore, as in his book "Rich Dad, Poor Dad," Kiyosaki describes the differences between assets and liabilities as they apply to balance sheets and income statements.
This book is a great financial tool for anyone who has had financial problems in the past (or currently), business people, investors, or anyone with a desire to have a greater understanding of what money is and how we can make it work for us instead of us always having to work for it (i.e. avoid being a slave to money both in terms of emotions and desires, as well as in our career lives and businesses).
Kiyosaki details the various types of Investors. He details 7 levels or 'types' of investors, and gets his reader to find out which level they currently operate on, and how they can move from one level to the another. And why, perhaps, a change in level is needed.
One of my favorite sections of the book is part 3 titled "How to be a Successful "B" and "I." In this part, Kiyosaki describes how to go from your current financial state to a better financial state with one short term goal and one long term plan (a 1 year goal, and a 5 year plan). Moreover, he describes the differences between that which is a risk, and that which is risky, how to work around your financial fears, making setbacks and disappointments into strengths, and choosing proper mentors to gain good financial advice. Overall, this is an excellent book to begin your personal financial growth, I highly recommend it.
