Not only do great entrepreneurs understand the problem, they understand all the effects of the problem. When I was promoting my solution to the student loan debt problem I described the problem similar to the blast zones of a bomb. I would draw out the immediate effects of the problem in expanding circles labeling the negative effects of each zone. I would also highlight the financial opportunities for expansion of my model at each zone. This is what makes a great entrepreneur, having the ability to fully understand a single problem and taking the time to map out the entire picture, including having the discipline to pursue avenues to failure as to know the outcome so they will know whether to continue or terminate that avenue in or out of their model. There are only two acceptable answers when an entrepreneur is asked about a problem. Yes there is a solution and Yes it is profitable. The problem with most VCs is they do not understand or cannot imagine the future the entrepreneur describes to them. Like most people, especially American VCs, they do not understand the best time to disarm a bomb is before it goes off.
