Robert Kiyosaki expresses in Cashflow Quadrant how each quadrant has different ideas, views and perspectives of money. Each quadrant, thus, is characterized by different concepts as they relate to money, business, and taxes. Robert Kiyosaki explains how employees have a job and work for someone else, a self employed person owns a job, a business owner owns an asset with produces money and cash flow, and investors have their money work for them.

In Cashflow Quadrant, Robert Kiyosaki uses personal experiences to identify the differences of each quadrant, and touches back on all the key concepts of Rich Dad, Poor Dad, in a repetitious way that is intended for readers of both books to have everything learnt reinforced.

Again, Robert Kiyosaki is about financial literacy, and repetition is a great way for ideas to stick.
In Cashflow Quadrant, you learn how the role you play, the quadrant your classified in will ultimately determine your financial freedom.
