The three core elements of success were as follows: One was leverage thinking. Everyone had limited resources at the beginning. To succeed, they needed to use the least resources in exchange for the greatest resources of others. They could make others have no choice but to accept them through exclusive possession, or use intangible products with extremely low Marginal Cost, or use the target to be deceived by ignorance, desire, and rules to reach an unfair transaction. The second was compound interest. It emphasized that the main problem behind focus and professionalism was compound interest. By continuously researching, exploring, and accumulating in a certain field, one could accumulate more experience and wisdom than others. By continuously accumulating in a field, one could go further than people who often jumped ship. The third was efficiency. It was not enough to only leverage thinking and compound interest. The method was also very important. If the method was wrong, it would generate more costs and revenge. If it could not be optimized, it would be impossible to compete with others. This required trial and error, improvement of management, reduction of resistance, and other methods to continuously improve efficiency. In the early stage, trial and error could reduce consumption. In the middle stage, resources could be maximized through management. Later, the relationship between politics and business could be improved to reduce resistance and maximize value.
