Which type of example is the one employed in the following paragraph？ The most important thing to becoming rich is for you to have a mindset to want to become rich. The reason I say that is this, is because I wanted to become rich when I played Monopoly, that was, I was nine years old. The greatest formula for wealth is found on that board game. When I was nine years old my poor dad, the schoolteacher says, “Ah, put the game away. Study, study, study! You’re wasting your time playing Monopoly.” And my rich dad said, “The formula, you must open your mind and see the formula right on Monopoly.” He said, “It’s right in front of you.” And I went, “What’s the formula？” And finally I learned the formula is: four green houses, red hotel, four green houses, red hotel. Today I’m a rich man because all I ever did since the time I was 24 years old was buy four green houses, sell them all, buy a red hotel. Four green houses, red hotel. It is not, you do not have to go to school to become rich. Just play Monopoly; four green houses, red hotel. That is it. Rich Dad’s Money Making Secrets
