Businesses

Kiyosaki emphasizes owning businesses that generate income passively, creating a system that works for you, not the other way around.

Real Estate 

Investing in income-generating real estate, like rental properties or flipping houses, is a cornerstone of Kiyosaki's strategy.

Paper Assets

Stocks, bonds, and mutual funds fall under this category.Understand these  instruments and add them to your portfolio.

Commidity

Investing in things like gold, silver, or oil can be a hedge against inflation and market volatility, according to Kiyosaki.

Intellectual Property

Owning things like patents, copyrights, or trademarks can generate ongoing income without much ongoing effort.

Notes & Mortgages

Kiyosaki emphasizes the importance of focusing on cash flow, the money that comes in and out of your investments, rather than just income itself.

Financial Education

Investing in your own financial knowledge is crucial, according to Kiyosaki.
