Robert T. Kiyosaki writes personal-finance and business self-help, best known for Rich Dad Poor Dad. The book contrasts two sets of financial attitudes through the figures Kiyosaki calls his 'rich dad' and 'poor dad', arguing for greater attention to assets, cash flow, entrepreneurship and financial education. Cashflow Quadrant extends the framework by dividing income into employee, self-employed, business-owner and investor categories, while later books repeat or expand related ideas about property, investing and work. Kiyosaki's style is anecdotal, repetitive and designed to challenge conventional assumptions rather than provide a detailed investing manual. His work fits personal finance, entrepreneurship and wealth-mindset self-help; readers should distinguish its broad principles from regulated financial advice. Read more Less
