For leaders to govern and govern well they must first master the art of self-leadership. Lessons learned can then be applied to regulate their families. In order to regulate their families they must first practice virtue in their own lives. In order to arrive at the practice of virtue, they must seek sincerity and purity of thought. In order to obtain purity of thought, they must first extend their knowledge gained through education and practical experience. The extension of knowledge lay in the investigation of things, a necessary step to advance one's understanding. Understanding and experience combine to increase ability to provide solutions, and then determine proper procedures to implement them to resolve difficult situations.
