" Commenting on Einstein's quote, rich dad said, "We all possess both a great spirit and a mediocre mind. The challenge in turning our ideas into a mil- lion dollar or even billion dollar asset is often the battle be- 232 Rich Dad's Guide to Investing tween our own great spirits and our own, often mediocre, minds. When I explain the B-I Triangle, which is the business structure that gives life to business ideas and is explained in the second part of this book, some people become over- whelmed by the amount of knowledge required to make the B-I Triangle work for them. When that happens I often re- mind them of the battle between their great spirits and mediocre minds. Whenever a person's mediocre mind begins to oppose their own great spirits, I always remind them of what my rich dad said to me. He said, "There are many peo- ple with great ideas but very few people with great amounts of money. The reason the 90/10 rule holds true is because it does not take a great idea to become rich but it does take a great person behind the idea to become rich. You must be of strong spirit and strong in your convictions to turn your ideas into fortunes. Even if you understand the process via which your ideas can become millions even billions of dollars, al- ways remember that great ideas only become great fortunes if the person behind the idea is also willing to be great. It is often difficult to keep going when everyone around you is saying, "You can't do it." You must have a very strong spirit to withstand the doubt of those around you. But your spirit must be even stronger when you are the person saying to yourself "You can't do that." This does not mean that you plough blindly on not listening to the good and bad ideas of your friends or yourself. Their thoughts and input should be listened to and often used when their ideas are better than yours. But at this moment, I am not talking to you about mere ideas or advice. ' What I am talking to you about is more than just ideas. I am talking about your spirit and the will to go on even when filled with doubt and out of good ideas. No one can tell you what you can or cannot do in your life. Only you can deter- Solving the 90/10 Riddle 233 mine that. Your own greatness is often found at the end of the road, and when it comes to turning your ideas into money, there are many times when you come to the end of the road. The end of the road is when you are out of ideas, out of money, and filled with doubt. If you can find in yourself the spirit to go on, you will find out what it really takes to turn your ideas into great assets. Turning an idea into a great for- tune is more a matter of human spirit rather than the power of the human mind. At the end of every road, the entrepre- neur finds his or her spirit. Finding your entrepreneurial spirit and making it strong is more important than the idea or busi- ness you are developing.
