In the book Rich Dad Poor Dad by Robert Kiyosaki, the author shares his personal experiences growing up with two very different father figures - his biological father (Poor Dad) and his best friend's father (Rich Dad). Poor Dad was highly educated, worked hard for a steady paycheck, and believed in traditional financial advice such as saving money, getting a good job, and buying a house. On the other hand, Rich Dad was a self-made millionaire who believed in taking risks, investing in assets that generate passive income, and continuously educating himself about money and business.
